摘　　要：本文提出了一个新的砼在二向受力下破坏准则，该准则和实际符合较好。分析选择了合理的钢筋砼结构非线性分析方法，编制出钢筋砼结构非线性有限元程序ＲＣＦＥＭ。用该程序分析了东江水电站坝后引水背管（钢村一钢筋砼结构）的两个模型结构，计算结果同模型试验结果吻合良好。In this paper a new concrete failure criterion under biaxial loading,which is more coincided with the experimental results,is proposed and the selected nonlinear finite element analysismethod of reinforced concrete structure is provided with an analysis program RCFEM.Using this program two model tests of diversion pipe at the toe of the dam in the Dongjiang Hydropower Station is analyzed and its calculation results is quite closed with the data of the model tests.
