摘要
用三维弹塑性有限元计算分析了瀑布沟土石坝混凝土防渗墙的应力变形特征.防渗墙的应力变形受到“边界效应”,墙顶、墙底的预留压紧量,墙土之间的相对剪切及廊道纵向刚度等因素的影响。为了改善防渗墙的工作性状,文中提出了几点建议。
Stress and deformation of concrete cut-off walls of Pobugou earth-rockfill dam isanalysed by 3-D FEM. The factors affecting stress and deformation of the concrete cut-off wallsare mainly the valley boundary, the value of RCV, the interaction between soil and the walls, andthe rigidity of the porch. In order to improve the performance of the walls, some suggestions areput forward.
