Modeling Lateral Sliding of Slope due to Liquefaction of Sand Layer

Abstract

The stability of a soil slope is analyzed based on the experimental results of a centrifuge test. The failure mechanism recorded in the model test closely resembled that which occurred in the field. Excess pore pressure generated in a sand seam sandwiched between two silt layers contributed to the lateral sliding. The slope angle was significantly reduced after the simulated earthquake. The experimental results are in accordance with the lateral sliding observed at Valdez during the Alaska earthquake of 1964.
