The safety factor method, numerical analysis, probabilistic reliability method and non-probabilistic reliability method are slope stability analysis methods. The safety factor method is a traditional method for evaluating slope stability, which is based on limit equilibrium theory. Numerical analysis method is the use of finite element software to simulate the damage through the mechanism of slope analysis, the slope of the damage before the damage and destruction in the state of stress and strain, From the theory for the slope can be clearly failure to provide a theoretical basis. In addition, a numerical analysis of slope stability analysis, using indirect methods can also be obtained for the slope safety factor. Assessment method is the soil parameter variability parameters as random variables large, small variability parameters as constants, through the analysis of traditional probability theory to solve the random variable obtained mean and standard deviation, then come to function of the mean and standard deviation of the function, and ultimately find the slope stability evaluation of the reliability indexβ. Borrow non-probabilistic reliability method is a variable range of parameters as the research object, calculate the final interval obtained by non-probabilistic reliability index value ofη.We can conclude that non-probabilistic reliability theory is superior to probabilistic reliability theory in the case of small samples, which is based on the probability of non-probabilistic reliability theory and reliability theory stability evaluation under different conditions of comparative analysis.
