Abstract

Two case histories were analyzed to determine the validity of using nonlinear numerical analysis methods together with simple and familiar descriptions of soil behavior to predict shaking-induced excess pore pressures and permanent deformations within soil. The first case focuses on the prediction of liquefaction during centrifuge testing of a silt layer underlain by sand. The second case involves the prediction of behavior of the Upper San Fernando Dam during the 1971 San Fernando earthquake. Results of both analyses show that consistent and reasonably accurate estimates may be made of the behavior of soil during seismic loading. The relative simplicity of the framework used in describing the stress-strain behavior of soil provides the approach with significant practical appeal.

Nonlinear Dynamic Effective-Stress Analysis of Two Case Histories

St. Louis, Missouri

Two case histories were analyzed to determine the validity of using nonlinear numerical analysis methods together with simple and familiar descriptions of soil behavior to predict shaking-induced excess pore pressures and permanent deformations within soil. The first case focuses on the prediction of liquefaction during centrifuge testing of a silt layer underlain by sand. The second case involves the prediction of behavior of the Upper San Fernando Dam during the 1971 San Fernando earthquake. Results of both analyses show that consistent and reasonably accurate estimates may be made of the behavior of soil during seismic loading. The relative simplicity of the framework used in describing the stress-strain behavior of soil provides the approach with significant practical appeal.
