柘溪水电站引水隧洞钢筋混凝土衬砌出现开裂 ,本文采用钢筋混凝土非线性随机有限元方法对隧洞钢筋混凝土衬砌结构进行了计算 ,求出了相对应的可靠指标 ,并对结构的可靠性进行了分析。
The cracking of the reinforced concrete lining of the diversion tunnel of Zhexi Hydropower Station appears cracking. In this paper, the nonlinear reinforced concrete nonlinear finite element method is used to calculate the tunnel reinforced concrete lining structure, the corresponding reliable index is calculated and the reliability of the structure is analyzed.
