Stability Analysis of an Earth Slope Based on Taylor Series Method

Due to the complicated theory of reliability analysis method and the high requirement of parameters statistics and model calculation, most reliability analysis methods are not conductive to engineering application. In order to solve this problem, a simplified method, can be used in slope stability analysis. The technique is based on factor of safety method. The procedure of applying this method in slope stability analysis is studied. The methods of calculating parameters standard deviation are summarized. Engineering application shows that Taylor series method is feasible and practical in slope stability analysis and it provides a new method for slope reliability analysis.
