摘　　要：滑坡稳定性评价影响因素较多,且多具模糊性和不确定性。利用模糊综合评价的理论,在分析影响滑坡的主要因子的基础上,建立了定量评价模型。综合考虑各方面因素的影响,对北川小河滑坡进行了稳定性评价,并与传统的刚体极限平衡法进行比较,验证了该方法进行滑坡稳定性评价的合理性与可靠性。There are many factors on the landslide stability evaluation, which have fuzziness and the uncertainty. By using the theory of fuzzy comprehensive evaluation, this paper quantitatively evaluated the main factors affecting landslide with comprehensive consideration on all aspects of factors. It also evaluated stability of XIAOHE landslide of Beiehuan, and compared with the traditional rigid body limit equilibrium method. The results show that the methods have rationality and reliability to evaluate the stability of landslide.
