APPLICATION OF VERTEX METHOD TO EVALUATION OF SLOPE STABILITY

Considering the uncertainty of the measurement data, the complexity of determining calculation parameters, the fuzzy character of describing the stability states in the analysis of slope stability, this paper introduces a new method called vertex method that can be used in the stability analysis of slopes. By using this method we can get a fuzzy set of FS (factor of safety) of a slope from some uncertain soil parameters, and then determine the stability states of this slope by a kind of classification method. Finally, a case study is demonstrated to describe the procedure of this method.
