摘　　要：模糊评判法作为一种评价边坡稳定性方法,其关键在于能否准确地建立评价模型,是否能准确建立模型的重点在于隶属度与各评价因子权重的确定。在实际工程中,几乎所有研究者都是采用专家打分法来定权重。虽然这一方法应用广泛,但是主观性太强,不够客观合理。采用判断矩阵分析法来确定评价因子的权重,用二级模糊评判对某工程实例进行计算分析,结果表明用该法确定权重简便,亦能较好反映边坡所处状态。The key of the evaluation method, as a method of slope stability evaluation, lies in the accuracy of the established judgment model, and the determination of the membership and the weights of the evaluation factors are important to the judgment model. In practice, the expert scoring method is widely used in weights determination, though the method is subjective. Judgment Matrix Analytical Method is used to determine the weights of the evaluation factors and Secondary Fuzzy Evaluation is used in the calculation and analysis of a real project. This method shows to be convenient and closing to the reality.
