摘要 简要概述了中心点法的基本思想。基于可靠度的分析,考虑了岩土体物理力学参数不确定性的影响,采用中心点法对核桃树沟滑坡进行稳定性分析计算,并与其它评价方法结果对比。理论计算分析得出:基于中心点法的稳定性系数和传统的定值法结果对比十分接近,能够较好地拟合客观工程实际,特别适用于状态函数为F(X1,X2,…,Xn)=R-S的斜坡稳定性分析,是未来斜坡稳定性研究发展的主要前沿方向之一。 The central point method is briefly introduced. According to the central limit theorem, the random varia-bles were assumed to follow normal distribution or lognormal distribution when the state function is nonlinear. The state function is expanded by Taylor' s series and then linearized in the adjacent of central point to deduce the ana-lytical expression of reliability. By using this method, the reliability index, damage probability, and median stabili-ty safety coefficient were obtained. As an illustration, the stability of Hetaoshu landslide was analyzed and predicted in consideration of the uncertainty of physical and mechanical parameters of rockmass. Through comparison, it' s concluded that the stability coefficient calculated by this method fits the engineering practice and is consistent with the result calculated by traditional valuation methods. In particular, it is suitable for slope stability analysis when the state function F(X1 ,X2,…. ,Xn) =R-S. It is one of the major frontiers of analyzing slope stability in the fu-ture.
