【摘要】 高土石坝遭遇强烈地震时会与坝面库水及坝内孔隙水发生动力流固耦合相互作用,分别从宏观坝水耦合系统和细观水土耦合系统两个角度对高土石坝坝水动力流固耦合理论的研究历史、主要研究成果和研究趋势进行了阐述评价。对宏观尺度的大坝与坝面库水流固耦合作用,主要从早期坝水相互作用模型、库水运动精细分析方法以及流固耦合系统坐标描述等方面做出评述;对细观尺度的坝内水土耦合作用,主要从早期解耦或拟耦合的水土动力分析方法、基于Boit动力固结理论的细观水土动力流固耦合,以及基于混合物理论的细观水土动力流固耦合等方面做出评述。综合两个尺度的流固耦合作用研究现状,建议对高土石坝建立水库-土石坝-孔隙水的宏细观整体动力流固耦合系统进行综合研究,并指出了当前高土石坝宏细观坝水动力流固耦合理论尚待继续深入研究的若干相关问题。更多还原

【Abstract】 The dynamic interaction will happen among high earth-rock dams,reservoir and pore water under a strong earthquake. This paper introduces the main research history,research results and research trends of water-soil coupling system for earth-rock dams from the macro-scale and micro-scale aspects. On the macro-scale dynamic coupling system,the early dam-water interaction model,sophisticated analytical methods of reservoir water and FSI coordinate system description are summarized,and on the micro-scale dynamic coupling system,mainly from the early water-soil decoupled dynamic analysis method,and the water-soil coupling analysis system based on the Boit’s theory and the water-soil mixture theory,ect. Combining the above two research aspects of soil-water coupling system,a macro-scale and micro-scale coupling system of reservoir-dam-pore water is proposed to study the dynamic behavior of high earth-rock dams comprehensively.Finally,the main problems on the macro-scale and micro-scale water-soil coupling theory and further research topics are put forward.更多还原
