Rosenblueth法在边坡可靠度分析中的应用
Application of Rosenblueth method in reliability analysis of soil slopes
摘要
Abstract
The Monte-Carlo method is time consuming when it is used to find the slip surface with the minimum value of the reliability index. This paper aims to compare the slip surfaces calculated with the minimum factor of safety (namely the critical slip surface) and minimum value of the reliability index (namely the critical reliability slip surface). A simplified Bishop method was adopted to calculate the safety factor for a given circular slip surface and to define the ultimate state function. The Rosenblueth method was used to determine the reliability index for the potential slip surface and the harmony search algorithm was used to alter the potential slip surface to find the critical reliability slip surface. The results show that the critical slip surface is identical to the critical reliability slip surface for homogeneous soil slopes, and the critical slip surface is considerably different from the critical reliability slip surface for the complicated soil slopes. The Rosenblueth method is recommended within the determination of the critical reliability of the slip surface.关键词
