| 摘 要： | 本文对现行规范关于结构承载能力验算表达式进行了进一步探讨，从传统刚体极限平衡法计算重力坝深层抗滑稳定问题三种方法的力学机理出发，推导了传统刚体极限平衡法用于可靠度计算的极限状态表达式，得出了现行规范规定的对结构承载能力验算表达式应该与之所导出的极限状态式在力学概念上应该相同的结论，在此基础上得出了抗力和作用函数的正确表达式。工程算例的计算结果表明，应用修正过的抗力和作用函数进行计算可以解决现行规范关于结构承载能力验算表达式存在的问题。

| Abstract: | This paper further discusses the limitations involved in the wedge stability analysis method specified in the Design Specification for Concrete Gravity Dams.From the mechanism of traditional rigid limit equilibrium method for solving deep slide of gravity dams,this paper deduces the limit state equations for reliability analysis applied to rigid limit equilibrium method.A correct expression of resistance and action is deduced finally.The computation results show that the limitations involved in the Design Specification for Concrete Gravity Dams may be solved by applying the expression of resistance and action presented in this paper. |
