摘要
Abstract
The analysis on CSG (cement sand and gravel)dam generally references linear elastic constitutive model or constitutive model of rockfill material to make approximations,but it cannot truly reflect the displacement and stress distribution characteristics of this dam type. According to the constitutive model of CSG material that has been put forward,the work behavior of CSG dam in storage period was studied. In this article the finite element numerical modeling and the overall body stability analysis for 7 kinds of CSG dam section had engaged in as to study the influence of section change on stress-displacement distribution characteristics and integral stability of this dam type. The results show that CSG dam possess good stability and security,and it proves steeper dam slope lead to better economic rationality but lowers the security.关键词
