The Reliability Analysis Of Slope Based On The Limit Equilibrium Theory

With the development of extensive engineering construction in our country,more and more engineering projects must face with slope problems, the research of slope engineering will unavoidaly meet a lot of uncertain factors,so the reliability analysis of slope becomes particularly important.However,during the course of analysis people get used to consider the reliability analysis mothed and the traditional stability analysis mothed separately,it may not only cause the antinomy of the two methods directly,but also increase the difficulty of analysis at the same time. In view of the above sitution,this article based on safety factor of the traditional slope stability analysis, combined with reliability theory to carry out the routine analysis of slope, provided the calculate mothed and expression formular of reliability index under new performance function.At the same time,considering of the fuzzy factors in the slope project,this article carried on the simple analysis of fuzzy reliability of slope, made some achivements of theoricial and realistic.
