More factors in slope stability quantitative assessment often result to repetition of some factors, thus it is important to optimize the factors for evaluation. The authors generalize and classify the factors affecting the large-scale slope stability to avoid the repetition of some indexes in evaluation model. Based on some improvements on the classic two-grade fuzzy comprehensive evaluation model, twi-fuzzy comprehensive evaluation method is applied to evaluate the large-scale slope stability of a hydroelectric station according to the grade of its evaluation indexes. This model takes account of the effect of influencing factors and it is proved that twi-fuzzy comprehensive evaluation model is practical and reliable. The result indicates that the most important factors influencing the slope stability are basic geological factors, among which slope-type and lithology are the more important factors influencing bank slope stability than others.
