在总结三峡电站坝后钢衬钢筋混凝土压力管道现行设计方法的基础上 ,采用钢筋混凝土非线性随机有限元的方法对该管道进行了计算 ,求得了各种钢筋配置下的可靠指标并对管道的可靠性进行了分析
On the basis of summarizing the current design method of the steel lined reinforced concrete pressure pipe after the dam of the Three Gorges Power Station, the pipe is calculated by using the nonlinear finite element method of the reinforced concrete. The reliable indexes under various steel bar configurations are obtained and the pipelines Reliability is analyzed
