Abstract

Abstract: For the study of rock slope stability evaluation method of the alpine high altitude region, 12 main evaluation indexes which influence the stability of rock slope in the special area were selected as the evaluation factors of fuzzy evaluation, to build fuzzy comprehensive evaluation model of the system in the alpine high altitude areas by applying of AHP method and fuzzy mathematics theory to determine the weight of each index and membership. Based on this model, the right bank of highway slope stability of the Pangduo Hydro Project was evaluated by fuzzy comprehensive evaluation. The evaluation results objectively reflect the engineering actual situation, which has some practical guiding significance and reference value to analysis and predict of rock slope stability in this kind of region.

Key words: geotechnical engineering;alpine high altitude region, AHP, rock slope, stability, evaluation index

摘要： 为研究高寒高海拔地区岩质边坡稳定性的评判方法，选取影响该类特殊地区岩质边坡稳定性的12项主要评判指标，作为模糊评判的评价因子，应用AHP方法和模糊数学理论确定各指标的权重和隶属度，从而构建高寒高海拔地区模糊综合评判体系模型。基于该模型对旁多水利枢纽工程右岸公路边坡稳定性作模糊综合评判，评价结果较为客观地反映了工程实际情况，对该类地区岩质边坡稳定性进行分析预测具有一定的指导意义和参考实用价值。
