Abstract：The analysis of slope stability is influenced by numerous factors with vagueness and randomicity. Although fuzzy comprehensive evaluation method is used to analyze slope stability，it is difficult to determine the weights of different factors appropriately，which are usually given by experts experientially. Thus，the application of the fuzzy comprehensive evaluation method is limited to certain extent. Considering the above-mentioned disadvantage，a multi-pole fuzzy pattern recognition model of subjective and objective weight determination is presented to analyze slope stability，in which the initial weights are given objectively by the alternative iteration model，and then，an appropriate adjustment may be made subjectively according to the simplified fuzzy decision method of two-element comparison. The importance of the expert and the advantage of the numerical calculation are fully considered in the model. The rationality of this method is shown by a comparative analysis of engineering case.
