Performance Of Fill Soils During The Loma Prieta Earthquake, J. D. Frost, F. A. Reyna, J. L. Chameau, P. Karanikolas
Performance Of Fill Soils During The Loma Prieta Earthquake, J. D. Frost, F. A. Reyna, J. L. Chameau, P. Karanikolas
International Conference on Case Histories in Geotechnical Engineering
The results of high quality in situ test results obtained at Hunter's Point Naval Station both before and after the Lorna Prieta earthquake are presented. The interpretation of these tests and the results of subsequent numerical ground motion analyses are validated by the observed response at that site during the event. Data show that densification of the loose fill soils occurred as a result of the seismic activity and corroborate the observed surface deformations.
Prediction Of Drilled Shafts Axial Capacities Using Cpt Results, O. M. Alsamman, J. H. Long
Prediction Of Drilled Shafts Axial Capacities Using Cpt Results, O. M. Alsamman, J. H. Long
International Conference on Case Histories in Geotechnical Engineering
Results from nineteen full-scale axial load tests are reviewed to compare methods for predicting axial capacities of drilled shafts using results of Cone Penetration Tests (CPT). The three methods to estimate failure loads are: (1) Nottingham method, (2) Laboratoire des Ponts et Chaussees method (LPC), and (3) the Poulos and Davis method. Comparisons are made to assess the accuracy and dependability of each predictive method. Analyses of results indicate that the LPC method provides the most reliable predictions for axial capacities of drilled shafts in clay.
Reanalysis Of A Vacuum Distillation Unit Foundation, M. N. Viladkar, Swami Saran
Reanalysis Of A Vacuum Distillation Unit Foundation, M. N. Viladkar, Swami Saran
International Conference on Case Histories in Geotechnical Engineering
This paper deals with the reanalysis of the foundation of an already existing Vaccum Distillation Unit in an oil refinery. The reanalysis is required to suggest if the existing foundation of the unit would be capable enough to withstand an additional pressure intensity to which it would be subjected due to proposed expansion of the unit. The paper therefore discusses the geotechnical investigation program undertaken for evaluating the relevant design parameters and the methodology adopted to compute the sustainable pressure of the foundation.

Rigid Vs. Flexible Pile Caps: Case Study For 235 M. Delhi T.V. Tower, H. R. Viswanath
Rigid Vs. Flexible Pile Caps: Case Study For 235 M. Delhi T.V. Tower, H. R. Viswanath
International Conference on Case Histories in Geotechnical Engineering
Foundation for the prestigious 235m. Delhi television tower commissioned in 1988 in New Delhi consists of 279 reinforced concrete piles of 500 mm diameter with 1250 KN load carrying capacity. The tower is resting on a circular pile cap 32 m. diameter with an average thickness of 2.5 m. Pile cap was designed assuming full rigid conditions at site. When it was noticed that the pile reinforcement was predominantly anchored to the layers of the pile cap reinforcement, it was apprehended that this arrangement does not ensure complete rigidity as assumed, but it makes it only partially flexible. This paper …
Taj Mahal – An Appraisal Of Foundation Performance, A. S. R. Rao, Swami Saran, S. C. Handa, G. Ramasamy, M. N. Viladkar
Taj Mahal – An Appraisal Of Foundation Performance, A. S. R. Rao, Swami Saran, S. C. Handa, G. Ramasamy, M. N. Viladkar
International Conference on Case Histories in Geotechnical Engineering
Because of severe restrictions placed by the National Authority, no authentic data on subsoil details below Taj Mahal - a protected monument - is available. For the first time, an attempt has been made to fill in gaps that exist in our knowledge of subsoil profile below the structure and present a plausible appraisal of foundation performance during the existence of the structure. Since details of foundations cited in literature on Taj Mahal really fall into the realms of architectural conjecture, in the present analysis, engineering intuition and judgement have gone into making certain premises regarding the probable type, dimensions …

International Conference on Case Histories in Geotechnical Engineering
Construction of the first phase of the South Parking Garage at the Tampa International Airport in Florida was completed in December 1991. A full-scale field load testing program was used in design of the drilled shaft foundations, with specific goals of determining the bond strength and characterizing the load-displacement behavior of the rock sockets. The displacement behavior and bond strength of the test shafts were predicted from elastic solutions and semiempirical methods. Input parameters included the rock uniaxial compressive strength and elastic modulus. The load test results are compared to the predictions herein, and the practical application of these comparisons …

Using back analysis for all working stages the peak and residual parameters caused by foundation failure were defined. The ratio of residual to peak value of …
The Performance Of Structures After Imposed Rotations, T. Amirsoleymani
The Performance Of Structures After Imposed Rotations, T. Amirsoleymani
International Conference on Case Histories in Geotechnical Engineering
After the initial full loading of two similar grain silos, which were built on silty sand, the Export-Import Building tilted toward the Working Tower and the joints between the two structures closed. The lateral force caused cracks in the columns of E-I Buildings. Two different methods were used to rotate the structure. The first method was based on the uneven loading of structures. The second method vas to remove thin layers of soil by chains under the foundations. The B-I Buildings were successfully rotated at both sites in 1989. The measurements for settlement and tilt were made to compare the …

Variation In Capacities Of Different Pile Types Under Similar Soil Conditions, H. Senapathy, J. R. Davie, M. R. Lewis
International Conference on Case Histories in Geotechnical Engineering
The interaction between soil and various pile types is of interest because it depends not only on the shear strength characteristics of the soil, but also on the pile dimensions, shape, and installation method, and on time after pile installation. This paper presents load test results from three types of displacement piles installed at the same site. The results obtained from the tests are compared with theoretical estimates. The computed values of soil-pile adhesion, back-calculated from the load tests, are discussed and compared with values found in the literature. Estimated pile capacities during driving and retap are also compared and …
Case History Of An Uplift Problem, J. R. Deutekom, R. J. Termaat
Case History Of An Uplift Problem, J. R. Deutekom, R. J. Termaat
International Conference on Case Histories in Geotechnical Engineering
Deformation and related stability problems of dikes in the western parts of Holland were for many years ascribed to creep and excess pore water pressures only. However in the spring of 1988 during a high water period in the river Rhine the so called uplift mechanism was for the first time measured in practice. It was then recognised that in some cases the problems have been caused by the uplift phenomenon. For a few years the pore water pressures and the deformations were observed in a test site. With the results of the observations a procedure was formulated for design …
Distress In Hirakud Dam, Orissa, India – Possible Causes And Remedial Measures, B. Ramachandran
Distress In Hirakud Dam, Orissa, India – Possible Causes And Remedial Measures, B. Ramachandran
International Conference on Case Histories in Geotechnical Engineering
Distress has been observed in the above dam, on its right spillway immediately after its completion in 1957. The distress has been intensified in the eighties with development of thin horizontal cracks in the undersluice barrels, gate gallery and adjoining areas at a level 18m above bed. These have all been chiselled, opened up and epoxy grouted; besides with water proof cement. But parallel cracks opened up soon after. Studies in detail carried out by various government organisations point out that rapid placement of concrete in ’55 - ‘56 leading to thermal stress is the main cause. Though some attribute …
Foundations For Large Embankments, F. Colleselli, G. Cortellazzo
Foundations For Large Embankments, F. Colleselli, G. Cortellazzo
International Conference on Case Histories in Geotechnical Engineering
This report deals with problems connected with the design and construction of two levees built on thick soft compressible soils in the Po Delta. Settlement and pore pressure measurements in foundation soils, taken for about four years during and after construction by means of complete geotechnical instrumentation, were compared with results obtained through various methods during both design and back-analysis phases. Back-analysis was carried out using numerical simulations with finite-element programs. Considerations of the problems of the global stability of the embankments during the various construction phases are also presented.
Geotechnical Problems Of Dam Sites And Their Solution With Reference To The Projects Of Eastern India, S. Gangopadhyay
Geotechnical Problems Of Dam Sites And Their Solution With Reference To The Projects Of Eastern India, S. Gangopadhyay
International Conference on Case Histories in Geotechnical Engineering
Geotechnical problems of dam construction are associated with adverse geological conditions of the dam site like soft rock, fault, shear zone, joints, weathering, permeable bouldery deposit, soluble rocks, ancient slide etc. In many of the dam sites of eastern India where one or more of such adverse conditions exist, the dam could be safely constructed by treatment of foundation defects. In some cases, however, a new site with less geologic problem was chosen with consequent modification in the project scheme.

Seepage Through Mine Tailings Dams, D. C. Cowherd, K. C. Miller, V. G. Perlea
International Conference on Case Histories in Geotechnical Engineering
A determination of the phreatic surface in dams constructed of coal refuse, under the criteria set forth in the National Dam Safety Act was made. All of these dams were over 20 years old. Most of the embankments studied were not constructed with any compaction specification and no effort was made to compact the coal refuse. A comparison of actual phreatic surface to the theoretically predicted surface is made using the classical seepage theory and the computer program SEEP. The embankments are old enough to present the steady slope phreatic surface, and thus, provide a good check of the ability …

Smw Wall For Seepage Control In Levee Reconstruction, D. S. Yang, U. Luscher, I. Kimoto, S. Takeshima
International Conference on Case Histories in Geotechnical Engineering
An SMW wall was installed as a cutoff wall for seepage control during high floods in a narrow levee constructed in the early 1900's using sandy soils. After part of the wall was installed, difficulties were encountered in evaluating the permeability of the as-built cutoff wall according to the project specifications. Methods used to evaluate the permeability of the cutoff wall included laboratory tests on bulk samples and core samples and in-situ permeability tests. Significant differences in test results were caused by various sample preparation and handling procedures, sampling disturbance, and different testing methods. The difficulties were resolved by performing …
Stabilization Of A Tailings Dam By De-Watering, A. B. Fourie, G. I. Mcphail
Stabilization Of A Tailings Dam By De-Watering, A. B. Fourie, G. I. Mcphail
International Conference on Case Histories in Geotechnical Engineering
The failure of the outer slope of one of the paddocks of a tailings dam, resulted in a significant decrease in the area available for tailings deposition. Overloading of the remaining five paddocks resulted. To maintain the stability of the existing dam whilst construction of new disposal facilities was in progress, three techniques were investigated; horizontal, push-in drains at the dam toe, a rock buttress around the operational paddocks, and vertical de-watering wells installed on the first terrace, or ‘step-back’ of the dam. De-watering wells proved most effective, and 165 wells were installed. A monitoring programme included regular determination of …

Comparison Between Finite Element Predictions And Results From Dynamic Centrifuge Tests On Tilting Gravity Wall Retaining Dry Sand, A. S. Al-Homoud, R. V. Whitman
Comparison Between Finite Element Predictions And Results From Dynamic Centrifuge Tests On Tilting Gravity Wall Retaining Dry Sand, A. S. Al-Homoud, R. V. Whitman
International Conference on Case Histories in Geotechnical Engineering
An analytical model is developed to analyze the seismic response of gravity walls retaining and founded on dry sand, with special emphasis on tilting behavior. A well verified two-dimensional finite element code is used for this purpose. The analytical model is verified comparing predictions to results from three dynamic centrifuge tests, with satisfactory agreement. Moreover, sensitivity analyses are carried out for one of the centrifuge test conditions to understand how the results would change if the boundary conditions and rotational stiffness of the wall were changed.

This study analyzed and compared computed and recorded responses of the building by using the state-of-the-art techniques for dynamic pile-group interaction. Computed results were in good agreement with recorded ones.
Earthquake-Induced Parameter Automation, Gregory L. Hempen, James L. Keim, James L. Mayo
Earthquake-Induced Parameter Automation, Gregory L. Hempen, James L. Keim, James L. Mayo
International Conference on Case Histories in Geotechnical Engineering
An operating automated system has been developed for Wappapello Dam. The system allows periodic reading of foundation pore pressure sensors. Upon sensing strong ground shaking the system reads rock and foundation triaxial acceleration. The acceleration readings cause the system to collect pore pressure rise in a loose, saturated sand. The data is available over telephone lines in real time. In addition to reducing maintenance piezometer reading labor, the automation performs earthquake triggering notification and remote data evaluation. The engineering use for dam safety review is considered invaluable.
Evaluation Of Liquefaction Potential Of Coal Slurry, D. C. Cowherd, K. C. Miller, V. G. Perlea, Shamsher Prakash
Evaluation Of Liquefaction Potential Of Coal Slurry, D. C. Cowherd, K. C. Miller, V. G. Perlea, Shamsher Prakash
International Conference on Case Histories in Geotechnical Engineering
Hundreds of coal refuse impoundments are constructed each year to dispose of coarse and fine coal refuse. As the need for more sites develops, the suitability of available sites decreases. This creates the need for alternative construction practices such as upstream tailings dam construction methods. These methods raise the question of how to analyze the seismic and liquefaction stability of these structures. The use of down hole nuclear density and moisture probes provides a reliable method for assessing the potential stability issues for these types of structures.
Ground Waving And Its Damaging Effect, John G. Z. Q. Wang
Ground Waving And Its Damaging Effect, John G. Z. Q. Wang
International Conference on Case Histories in Geotechnical Engineering
Some unusual patterns of earthquake damages due to ground waving have been described in order to draw attention to further research towards these problems. A brief introduction of relevant theoretical approach to torsional components of ground motion and amplification of seismic surface waves due to local topographic irregularities have been given in this paper to provide a contrast between theoretical approach and practical cases in order to reflect the gap to be filled.
