台阶形岩石基础及厂坝联合结构的应力计算研究

Study on stress calculation for the structure with step rock foundation and block power plant

摘要: 按混凝土材料线弹性和弹塑性两种应力－应变关系模式，对某河床式电站厂坝及岩基结构进行了三维受力比较分析，得出了正常工作情况下各典型部位的应力大小，其结果已被该工程设计所采用。

Abstract: In this paper,comparison of three dimensional load bearing is conducted between the structure of block power plant and rock foundation, according to two models of linear elasticity and elastoplastic concrete. The stress values for each typical part of this structure are derived. The result is adopted in project design.
