MODELING LATERAL SLIDING OF SLOPE DUE TO LIQUEFACTION OF SAND LAYER

The stability of a soil slope is analyzed based on the experimental re sults of a centrifuge test. The failure mechanism recorded in the mode l 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 i n accordance with the lateral sliding observed at Valdez during the Al aska earthquake of 1964.
