Abstract

Abstract: In order to study effectively about the foundation treatment method for Sanhekou arch dam, by use of nonlinear finite element analysis, the deformation of dam body and foundation, yield state and degree of safety before and after the treatment of the main weak interlayer were studied. Based on the nonlinear results, anti-sliding stability of the potential slide block was analyzed. Accordingly, engineering treatment measures for the main fault were advanced.

Key words: nonlinear, overload, rigid body limit, foundation treatment

摘要： 为有效研究三河口拱坝的地基处理方法，采用非线性有限元法对比分析了软弱夹层处理前后坝体和基础的变形、屈服状态和安全度，根据非线性成果进一步分析了抗力体潜在滑块的抗滑稳定性，依据以上成果提出了主要断层的工程处理措施。

关键词: 非线性, 超载, 刚体极限, 地基处理
