Understanding and assessing the spatial extent of liquefaction hazard requires the spatial dependence of geotechnical properties to be taken into account. In this work, novel multiscale random field models will be developed to characterize and quantify spatial variability of geotechnical parameters across scales. Such models will then be integrated with a simplified procedure for the probabilis...

Dam monitoring relies on the long-term measurement of small structural motions at regular intervals. Traditional surveying techniques and geotechnical instrumentation can effectively monitor oneor twodimensional modes of motion. However, spatial distribution of geotechnical instrumentation is usually limited to the locations that the instruments can be installed during dam construction, whilst ...

This research paper presents a compendium of the geotechnical sub-soil data profiling and zoning of the major urban settlements of Peshawar using Geographic Information System. Significant geotechnical properties of the under study area soils i.e., Zone 5 & 6 in Peshawar were assessed through one hundred and three different standard penetration test reports up to the depth of 1 m and 3 m. The q...

As physical modeling sees increasing use in geotechnical engineering education, there is a need for a strategic approach for integrating this powerful simulation technique into courses in a way that ensures the greatest benefit for students. For this reason, a learning theory approach, which recognizes the natural learning cycle of students, has been developed. The approach is based on a modifi...

John S. McCartney received BSCE and MSCE degrees from the University of Colorado Boulder and a PhD degree in civil engineering from the University of Texas at Austin. Dr. McCartney’s research interests include unsaturated soil mechanics, geosynthetics, and thermally active geotechnical systems. He has received several research awards, including the NSF Faculty Early Development (CAREER) Award i...

The finite-element (FE) method is widely recognized as a powerful tool in modeling structural and geotechnical systems and simulating their response to static and dynamic loads. In addition, numerical optimization is commonly used in many engineering applications, such as structural reliability analysis, FE model updating, structural identification, and structural optimization. This paper focus...

It is the essence of geotechnical design to obtain soil parameters for design that are different from a site to another. Therefore, soil investigations play very important role in geotechnical design. The modeling of the ground based on investigation results is called site characterization, and there are some new developments in this area based on statistical theories. In the new approach, the ...

The Jackson Lake Dam was constructed in 1917 in the Grand Teton National Park near Jackson, Wyoming. The dam was a hydraulic fill placed on a natural alluvium and outwash foundation. The Bureau of Reclamation (Burec) determined that the dam and its foundation would be susceptible to liquefaction and failure during a potential earthquake; a series of contracts was let to remove and replace the d...

The Konjsko tunnel is an integral part of the Zagreb-Split-Dubrovnik highway, section Prgomet-Dugopolje. It consists of two tunnel tubes having 1326.0 and 1133.8 meters in length. The greatest overburden amounts to 150 m. This paper presents geotechnical measurement results and back numerical analyses. Back numerical analyses in combination with geotechnical measurements enable safer and more r...

ABSTRACT: Recently, limit state design (LSD) in geotechnical engineering has been developed through LRFD in North America and Eurocode 7 in Europe. LRFD is an approach that estimates resistance by design model and that multiplies resistance factor by calculated resistance to reflect the uncertainty of materials and design models. Whereas, Eurocode 7 employs the partial resistance factor applied...
