A Comparison Of Three And Two-Dimensional Analyses Of Rockfill Dams In Narrow Valleys (A Case Study: The Vanyar Dam), Mehdi Derakhshandi, Mojtaba Honarmand, Amir Hossein Sadeghpour

International Conference on Case Histories in Geotechnical Engineering

A two-dimensional analysis of the largest cross-section of earth dams may generate appropriate results provided that the dam is located in a U-shape valley. The Vanyar dam has been constructed in a narrow valley. With regard to the geometrical consideration of the valley, there is no plane strain condition throughout the long side of the dam. In this research, the results of three and two dimensional numerical analyses of the Vanyar dam are compared in terms of settlement, pore water pressure, and total vertical stress. These analyses were carried out by a finite difference method through FLAC-3D and FLAC-2D softwares. …


A Non-Linear Method To Estimate Elastic Settlement Of Shallow Foundations Using Small-Strain Stiffness, Reza Amini Ahidashti, Abdolhosain Hadad Apr 2013

A Non-Linear Method To Estimate Elastic Settlement Of Shallow Foundations Using Small-Strain Stiffness, Reza Amini Ahidashti, Abdolhosain Hadad

International Conference on Case Histories in Geotechnical Engineering

In this paper, we investigated how to utilize the small-strain stiffness order to estimate the settlement of shallow foundation on granular soils. For this purpose, a power law equation between normalized shear modulus and shear strain was presented. Based on elasticity theory and proposed equation, a new method in term of small-strain stiffness was suggested order to estimate the immediate settlement. In order to evaluate the proposed method, a series case history was studied, that included the loading tests and seismic geophysical tests. These field measurements are compared to the predicted values. The result indicated that the proposed method in …

This case model examination is intended to structure a new program for managing the Bihari embankment infrastructure. Similar to many historical flood control initiatives throughout the world, India’s embankment infrastructure shows the effects of aging and multi-purpose use of the facilities. To examine what …


An Example Of Teaching Slope Stability From True Case Histories, Diego Lo Presti Apr 2013

An Example Of Teaching Slope Stability From True Case Histories, Diego Lo Presti

International Conference on Case Histories in Geotechnical Engineering

The use of case histories in classroom mainly involves an inductive teaching approach. This paper discusses the intrinsic advantages and possible drawbacks of such an inductive approach. More specifically, the paper illustrates an example of teaching the class of “slope stability” based on such methodology. The class takes place at the University of Pisa in the second tier degree of Civil Engineering of Infrastructures. The inductive teaching approach is very popular in the British/American Higher Education system. On the contrary it is not so popular in Latin countries like Italy. In order to make more clear the comprehension of this …


Application Of Observational Method In The Successful Construction Of Underground Structures, Sardar Sarovar (Narmada) Project, Gujarat, India, Indra Prakash Apr 2013

Application Of Observational Method In The Successful Construction Of Underground Structures, Sardar Sarovar (Narmada) Project, Gujarat, India, Indra Prakash

International Conference on Case Histories in Geotechnical Engineering

The Sardar Sarovar (Narmada) underground powerhouse is located in Deccan Basalt flows in the lower Narmada valley in Gujarat state. These flows are intruded by dolerite dykes and sill. Basalt flows and dolerite rocks are considered good tunneling media for locating underground structures. Therefore, initial designing of supports was done considering good rock mass conditions. However, during construction numerous geotechnical problems were encountered necessitating review of support system. Rock falls and collapses were observed in tunnel sections passing through dolerite dykes and sills. Cracks were observed in the walls of the powerhouse cavern. During progressive excavations back analysis was done …

Behaviour Of A Large Anchored Basement In Dense Sands And Gravels, Francesco Petrella, Roberto Persio, Silvia Ferrero, Tim Hocombe

International Conference on Case Histories in Geotechnical Engineering

Prior to the excavation of half a million cubic meters of dense gravelly material within the city centre of Milan, a 24 to 27m long diaphragm wall was built to provide a 17m retained height to a four-level basement. Temporary support was offered by two to four rows of ground anchors with the exception of a portion adjacent to an existing multi-level cark park where a post-tensioned capping beam was installed to protect the car park and prevent it from being subject to sway. Other design challenges were posed by the proximity of a buried channel and of an urban …


Calibration Of Numerical Model For Liquefaction-Induced Effects On Levees And Embankments, Michelle Shriro, Jonathan D. Bray Apr 2013

Calibration Of Numerical Model For Liquefaction-Induced Effects On Levees And Embankments, Michelle Shriro, Jonathan D. Bray

International Conference on Case Histories in Geotechnical Engineering

Soil liquefaction presents a significant hazard to the built environment. The seismically induced permanent displacement of earth levees, dams, and embankments resulting from liquefaction below these earth structures is not well captured in current seismic design practice. The objective of this study is to advance the capabilities of numerical methods toward the solution of problems involving limited lateral spreads. The nonlinear soil constitutive model UBCSAND, as implemented in the finite difference program FLAC, (Itasca), is used to evaluate the seismic deformations of the newly-constructed Moss Landing Marine Laboratory (MLML) in Moss Landing, California resulting from liquefaction-induced lateral movements during the …


Case Histories In Geotechnical Engineering Education, James Mahar Apr 2013

Case Histories In Geotechnical Engineering Education, James Mahar

International Conference on Case Histories in Geotechnical Engineering

Case histories can be taught as an individual course or as part of a specific engineering class. These studies are very important when the teaching methodology incorporates the observational approach in design and construction. Several resources for case histories are available. However the most insightful are those in which the instructor has personal knowledge or the student participates in a case history-type project. One of the most important elements in engineering education is the sequential design approach in civil works projects. Case histories provide a very effective means of illustrating the complete design process which is the framework of professional …


Case History — Performance Monitoring Success, Charles B. Grant, Tom Hurley Apr 2013

Case History — Performance Monitoring Success, Charles B. Grant, Tom Hurley

International Conference on Case Histories in Geotechnical Engineering

The City Creek Center urban redevelopment project in Salt Lake City, Utah involved excavations up to 65 feet deep. Shoring systems included more than 29,000 square feet of anchored diaphragm walls, 100,000 square feet of soil nail walls, and 860 linear feet of underpinning. Detailed performance monitoring alerted the project team to unacceptable performance of an anchored diaphragm wall adjacent to an occupied twenty-five-story building on shallow foundations. This knowledge allowed the team to react quickly, stabilize the excavation, investigate the situation, and develop successful remedial measures. The diaphragm wall was reinforced with additional anchors and subgrade concrete struts, allowing …

Composite Shallow & Deep Foundation In Karst Geology For The Countryside Christian Center New Sanctuary Clearwater, Florida, Said Iravani Apr 2013

Composite Shallow & Deep Foundation In Karst Geology For The Countryside Christian Center New Sanctuary Clearwater, Florida, Said Iravani

International Conference on Case Histories in Geotechnical Engineering

Evaluation, design, construction, and monitoring of foundations in karst geology are challenging tasks. The random presence of karst features, the variation in size, extent, and depth of karst features, and the different origin and geological characteristics of karst features make site characterization and investigation difficult. A balance between non-intrusive filed tests is useful to improve the site characterization. Non-intrusive field tests which provide multi-dimensional mapping such as Electrical Resistivity Imaging (ERI) or Ground Penetrating Radar (GPR) can provide spatial coverage instead of point data. Non-intrusive field tests which are not sensitive to moisture such as shear wave velocity measurements can …
