Abstract: Several ground improvement techniques, which have been proven to be effective and economical solutions for increasing the lateral stiffness and strength of weak soils around piles, can often result in unnecessarily ...

Abstract: The use of p-multipliers in the analysis of the lateral loading behavior of pile groups is based on the concept of modifying the single-pile p-y curve to obtain the p-y curve for a pile in a group. The p-multipliers account ...

Abstract: pressure generation and dissipation during and after an earthquake, utilizing the method presented herein to obtain the necessary input properties, is presented in a companion paper (Arulanandan and Muraleetharan 1988)....

Abstract: Current methods for level ground soil‐liquefaction analysis involve the use of a stress ratio required to cause liquefaction obtained from laboratory testing of small element samples. Limited field evidence and considerable ...

Abstract: Unsaturated soils are three-phase porous media consisting of a solid skeleton, pore water, and pore air. The behavior of unsaturated soils is strongly influenced by the matric suction (pore air pressure minus the pore water ...

Abstract: Following the comprehensive model formulation given in Part I, a fully implicit integration procedure for the rate equations using a closest point projection method is presented in this paper. The stress-update algorithm ...

Abstract: Liquefaction of unsaturated sands has been observed in laboratory tests and in the field. A comprehensive investigation of unsaturated sand deposits subjected to seismic loading, especially using validated computational ...
