【摘要】 根据动水压力对心墙堆石坝地震响应的影响问题,将上游坝体模拟为固液两相孔隙介质,用以固相位移和液相压力为基本未知量的Biot方程进行分析,建立了坝体—水体—地基耦合系统的动力反应分析模型.更多还原

【Abstract】 In this paper,a model for the dynamic response analysis of dam-water-foundation coupling system is constructed.Some parts of the earth-rockfill dam are treated as a two phase of fluid-solid porous media and the Biot dynamic equations are solved for solid-phase displacement and fluid pressure by the scheme.更多还原
