摘要
我国正在开展强震区超深厚覆盖层上建坝工作,深厚覆盖层上高土石坝地震反应分析方面仍存在问题亟待解决。从高土石坝及周围地层初始物理力学状态的描述,地震动输入机制,筑坝材料、覆盖层材料和各种接触面本构模型,边值问题求解四个方面对已有研究基础进行了总结评述,在此基础上,从理论方法、技术手段和规律机理3个层面对深厚覆盖层上高土石坝地震反应分析研究进行了展望。
China is carrying out the construction of dams on ultra-deep overburden in strong earthquake areas,and there are still problems to be solved in the seismic response analysis of high earth-rock dams on deep overburden.The existing research basis from four aspects are reviewed,including the description of initial physical and mechanical state of high earth-rock dam and surrounding strata,the ground motion input mechanism,the constitutive models of dam-building materials,overburden material and various contact surfaces,and the solution of boundary value problem.On this basis,the seismic response analysis of high earth-rock dams on deep overburden is prospected from three levels of theoretical methods,technical means and regular mechanisms.
