EXPERIMENTAL STUDY ON EXCESS PORE WATER PRESSURE OF SOILS COVERED BY CLAY LAYER
粘性土覆盖层下土中超孔隙水压力的动力试验研究

Experimental study is made on soil-structure interaction by shaking table tests. The development of excess pore water pressure in sandy silt and medium sand covered by clay layer under simulated earthquake excitations, and their consolidation behavior shortly after the simulated earthquake excitations are studied. The development mechanism of excess pore water pressure in saturated sandy silt covered by clay layer is analyzed. In the end, some main factors are pointed out to affect liquefaction potential of the soil covered by clay layer.
