【摘要】 以土-结构动力相互作用体系的模拟地震振动台模型试验为基础,考察了粘性土覆盖层下的粉土及砂土在模拟地震中的超孔隙水压力增长规律,及其震后的短期固结行为特征。分析了覆盖层下土体在地震中的超孔隙水压力发展特征机理,并探讨了影响超孔隙水压力发展的主要因素。更多还原

【Abstract】 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.更多还原
