ABSTRACT

This chapter considers the influence of the design parameters on slope safety and stability factors, which include water, anchor parameters and soil properties. The fuzzy utility value, function and the importance of each possible affecting factor on the slope stability are determined by using Fuzzy Multiple Attribute Decision Making Buckley. The safety margin of retaining structure is taken as the objective function. The dynamic stability analysis models of retaining structure are established. In actual stability, the objective function and constraint conditions are hard to perform in classical decision model and take on the fuzziness in most cases. The analysis of the dynamic stability of the prestressed structure bolting is performed by using MATLAB software package to calculate the minimum safety of the slope and find the most dangerous sliding surface location. Bolt length, bolt spacing and bolt angle are the important factors in the slope stability.
