| 摘 要： | 从土塑性极限分析上限定理出发,以土质边坡塑性极限分析条分法为基础,在引入可靠性分析方法(JC法)后,建立了土质边坡塑性极限分析条分法可靠度极限状态方程,并推导得到了塑性极限分析条分法可靠度计算公式。这种方法实现了定值计算向不确定性计算的转变,同时可靠度指标的计算结果具有概率的意义。

| Abstract: | Based on the limit analysis upper bound theorem of soil plasticity mechanics and the traditional slice methods,this paper establishes the limit state equation of plasticity limit analysis slice techniques.According to the equation,the calculation formulas of reliability index are obtained. This method can achieve the change from definite value calculation to deconfirmative calculation.Moreover,the use of reliability index to evaluate slope stability has meaning of probability. |
