Motion and Stability of Saturated Soil Systems under Dynamic Loading.
Abstract
Various theoretical models were examined in the light of recent developments in the theories of interacting continua. Computer programs were developed to implement the popular 'engineering' approach to liquefaction. Ghaboussi's incompatible finite element model was compared with higher order elements to select the best model based on accuracy and economy. Numerical performance of special finite elements to model line singularities that occur at free draining loaded surfaces just after application of the load was documented. Biot's theory of wave propagation in fluid-saturated media was implemented in a computer program following Ghaboussi and Wilson's procedures for linear elastic soils. The computer models were verified against available results in the literature on the subject and against theoretical solutions, for one-dimensional problems, based on Biot's theory. Work was started on setting up laboratory experiments for verification of the theory. Necessary equipment and instrumentation was acquired. (Author)
