Assessment Of Earthquake Size From Rock Fracture Dimensions Of Seismic Source In Geotechnical Earthquake Engineering Investigations, L. S. Srivastava
Assessment Of Earthquake Size From Rock Fracture Dimensions Of Seismic Source In Geotechnical Earthquake Engineering Investigations, L. S. Srivastava
International Conference on Case Histories in Geotechnical Engineering
The paper presents two case histories of rock fractures resulting in strong ground motion. Case I describes the November 27, 1971 rock burst involving 270 m long rupture with displacement of 15 mm in Nundydroog mine in Kolar Gold Field in Karnataka State, India, which resulted in damage to buildings on the surface and underground works in the mine. The event was recorded as an earthquake by seismic stations and the computed magnitude ml = 3.9 of the rockburst compares well with magnitude mb= 4.6 determined from the recorded seismogram. Case II describes April 5, 1976 rock …
Behavior Of Some Earth Dams On Liquefiable Soil, A. Popovici, V. Perlea, L. Corda
Behavior Of Some Earth Dams On Liquefiable Soil, A. Popovici, V. Perlea, L. Corda
International Conference on Case Histories in Geotechnical Engineering
The 1977 March 4 Vrancea earthquake emphasized several zones with liquefiable materials on Romanian territory. Some earth dams of such zones, placed to over 200 km from the earthquake epicenter were damaged. Important hydropower works are at present in different design or construction stages in such area, comprising long earth dams. The Seismic analysis procedure applied to their design was based on the finite element method. Some characteristic cross - sections of the earth dams in different versions have been studied. The analysed sections had different shapes (with and without stabilizing benches downstream) and included different zoning of the materials …

Post-Earthquake Failure Of A Tailings Dam Due To Liquefaction Of Pond Deposit, Kenji Ishihara
Post-Earthquake Failure Of A Tailings Dam Due To Liquefaction Of Pond Deposit, Kenji Ishihara
International Conference on Case Histories in Geotechnical Engineering
At the time of the Izu-Ohshima-Kinkai earthquake of January 15, 1978 in Japan, two darns retaining tailings from Mochikoshi gold mine failed, leading to a release of a large volume of tailings. One of the darns, No.1 dike, collapsed almost simultaneously with the shaking of the main shock, but another darn, No.2 dike, failed about 24 hours later at a time when there was no shaking. The failure of the No.1 dike is known to have been triggered by the liquefaction which developed in the tailings deposit in the impoundment pond. The cause of the failure in the No.2 dike …
Seismic Motion Selection Criteria For Dam Design, G. Rodolfo Saragoni
Seismic Motion Selection Criteria For Dam Design, G. Rodolfo Saragoni
International Conference on Case Histories in Geotechnical Engineering
In recent years, new seismic design methods for earthdam, based on finite element have been used. These methods generally require selection criteria of seismic ground motion to be used for the design. Most standard criteria used are maximum ground acceleration and linear response spectra. These criteria fail to predict seismic dam response due to strong nonlinear soil behavior characterized by large permanent displacement, shear modulus degradation and damping increasing with shear strain deformation variation, increase of water pore pressure and large variation of natural period of dam. A criterion based on the potential destructiveness of earthquake motion is proposed. This …
Seismic Response And Liquefaction Analysis By An Approximate Method, M. Hyodo, T. Yamanouchi, J. Hashizume
Seismic Response And Liquefaction Analysis By An Approximate Method, M. Hyodo, T. Yamanouchi, J. Hashizume
International Conference on Case Histories in Geotechnical Engineering
Presented is a simplified procedure for performing the dynamic effective stress analysis. An equivalent linear method is applied to the procedure. It is assumed, in this method, that the variations of the shear modulus and damping factor due to strain level and effective stress are independent one another. That is, firstly the total stress analysis is done in order to obtain the effective strain. Then the effective stress analysis is carried out and the moduli are varied due to the variation of the effective stress only. The accuracy of the result is checked by comparing it with that of nonlinear …
Surface Damage Of Tangshan Earthquake And Characteristics Of Response Spectrum Of Ground Movement, S. D. Zhao, H. Q. Fang
Surface Damage Of Tangshan Earthquake And Characteristics Of Response Spectrum Of Ground Movement, S. D. Zhao, H. Q. Fang
International Conference on Case Histories in Geotechnical Engineering
The intensive ground movement of seismic region was an essential factor in causing ground damages. Damages in historical events signified that the extent of destruction not only conformed to the epicentral distance but also related to geomorphology, soil type and ground structure. Different combination of ground lithology may reflected directly the enhancement and attenuation of seismic wave during its propagation and it had also dominating influence on ground movement, different damages and seismic excitation of the same ground. Hence the amplitude and type of seismic response spectra were determined. In this paper, ground movement and damage feature on geomorphology units …

The analysis and design aspects of this inter-disciplinary problem are illustrated with two typical design case studies selected from authors’ own experience in this specialised field. The …
Forge Hammer Foundation On Dilative Soil, S. J. Yang
Forge Hammer Foundation On Dilative Soil, S. J. Yang
International Conference on Case Histories in Geotechnical Engineering
The property of dilative soil will further change when the dynamic force with different frequency acts on soil surface. So far, the physical process of this change remains unknown. However, it has been observed in the field test that dynamic force would increase the amount of the crevice of dilative soil and destroy the soil by combining with the external water.
Foundation-Bearing-Rotor Interaction Problem In Controlling Vibrations In A 120 Mw Turbo Generator, Krishen Kumar, Shamsher Prakash
Foundation-Bearing-Rotor Interaction Problem In Controlling Vibrations In A 120 Mw Turbo Generator, Krishen Kumar, Shamsher Prakash
International Conference on Case Histories in Geotechnical Engineering
A two-pole turbogenerator posed problem of resonance and excessive vibrations at the operating speed during test runs in the Test-bed. The entire system comprising the foundation, pedestals supporting the generator, journal bearing seats, bearing oil-film, and the rotor has been modeled and analysed for computing the rotor's critical speeds as also the foundation's natural frequencies. Some of the system's parameters have been derived from actual tests. Sensitivity analysis for the rotor's critical speed that coincided with the operating speed of machine showed that this critical speed is relatively insensitive to the foundation mass as well as stiffness, and largely depends …

Vibration Studies Of Block Type Machine Foundations, S. K. Guha
Vibration Studies Of Block Type Machine Foundations, S. K. Guha
International Conference on Case Histories in Geotechnical Engineering
Detailed vibration measurements were undertaken at eight block type machine foundations with different supporting soil conditions. These extensive measurements were supplemented by theoretical vibration calculations using principally Barkan's method but, at times, using methods of Reissner, Pauw, Richart and Ford and Haddow. The results of prototype experiments and theoretical studies on various compressor foundations described above as also on similar foundations in the country justify broadly the validity of various theories, particularly Barkan’s method, though these are based on somewhat different concepts. Design criteria for foundations are generally described in terms of limiting values of amplitudes of displacement at the …

A Case Of Singular Geotechnical Failure For Industrial Structures In The Peruvian Andes, A. Carillo Gil, R. Torres Vega
A Case Of Singular Geotechnical Failure For Industrial Structures In The Peruvian Andes, A. Carillo Gil, R. Torres Vega
International Conference on Case Histories in Geotechnical Engineering
During the rainy season of 1982, foundation distress was occurred at several recently completed and still incomplete structures of an important mine project located in the Peruvian Andes. When the tailings thickener was tested an unexpected settlement started, some cracking was observed in the slab, and the central pier settled and tilted. The nature of the distress suggested the failure occurred as the result of the combined effect of a long term seepage under the bearing foundation soil and due to its different degree of compaction. This paper presents the characteristics of these problems as both foundation and fill materials, …
A Dockwall Failure In Milwaukee, Wisconsin, A. B. Wagner
A Dockwall Failure In Milwaukee, Wisconsin, A. B. Wagner
International Conference on Case Histories in Geotechnical Engineering
In 1975, a dockwall at the Port of Milwaukee, Wisconsin failed as salt was being deposited behind the wall. In 1981, exploration at the site was required for a new development. The exploration program included field testing to measure the shear strength of the organic soils through which the failure occurred. Dutch cone and vane shear devices were used. Continuous undisturbed samples were obtained in two (2) borings. This allowed an accurate determination of the stratigraphy in the slide area. The shear strength of the undisturbed samples was measured in the laboratory by means of the Torvane device. The shear …

Geotechnical Investigations For Foundation Design For Multi-Storeyed Building, S. C. Handa, Swami Saran, G. Ramasamy, A. S. R. Rao, B. Prakash
International Conference on Case Histories in Geotechnical Engineering
Oil and Natural Gas Commission of India plans to construct a multi-storeyed building in Dehradun city at the foothills of Himalayas. The geotechnical investigations were carried out at site to determine soil parameters for foundation design. It was found that it was not possible to provide a raft foundation for the building and hence alternatively the pile foundation was suggested. The pile load capacity was predicted on the basis of soil parameters determined and a comparison was then made with the results obtained by carrying out load tests on constructed piles.

Then based on the site tests and wave theory, the formula for calculating the attenuation of amplitude, the principles for selecting the site of a factory and the necessary distances …
Behavior Of Two Big Rockfill Dams, And Design Aims, V. F. B. De Mello
Behavior Of Two Big Rockfill Dams, And Design Aims, V. F. B. De Mello
International Conference on Case Histories in Geotechnical Engineering
The case histories of two major compacted embankment dams are analysed with regard to the problem most amenable to reasonings and computations of statistics of averages, the problem of deformations, discussed regarding specific laboratory testing compared with use of generalized correlations. Improved mental models for predictions are proposed. In the earthcore-compacted rockfill section the problem of crest cracking suggests the interest in a significant change of zoned section in the topmost stretch. For the concrete-face rockfill dam it is suggested that one needs a significant revision of instrumentation and monitoring orientation. Both dams behaved extraordinarily well on questions of consequence …
