摘要
采用极限应变准则作为极限状态方程 ,运用改进的 JC方法分析了地下隧洞稳定的可靠度。由于准则方程的高次非线性和复杂性 ,文中利用复合函数求导法则 ,直接针对基本随机变量求解。通过算例分析 。
In this paper the limit strain criterion is used as a limit state function and an improved JC method is used to calculate the reliability index of the stability of the tunnel. Because of the complexity and high order nonlinear property of the criterion, a derivative method for compound function is used to get reliability. By analysis of the example, some information is obtained. [
