Numerical Modeling of Liquefaction-Induced Slope Movements
This paper presents the calibration procedure and results from numerical evaluations of liquefaction-induced slope movements. A methodology is developed for the calibration of nonlinear effective stress models that focuses on liquefaction triggering and post-liquefaction accummulation of deviatoric deformations. A centrifuge test and a case history involving sloping ground conditions are analyzed to validate the ability of the calibrated effective stress model to predict liquefaction induced slope movements, showing favorable results. Subsequently, the calibrated constitutive model is used in forward estimates of liquefaction-induced lateral demands to assist with vulnerability evaluations of an existing immersed tunnel and conceptual design for the foundation of a suspension bridge near an active fault with large magnitude potential.
