摘要/Abstract

摘要： 将关键块体理论与模糊理论相结合，对于岩质边坡的稳定性进行了综合评价.选取抚顺露天矿南帮典型坡段，对岩坡的物理力学参数进行测定，并运用自主研发的关键块体搜索系统——GeoSMA-3D (Geotechnical Structure and Model Analysis-3D)进行关键块体的搜索与表征，根据表征特点进行评价参数的选择，最后运用基于AHP的模糊综合评价技术，引入总体稳定性系数，对边坡稳定性进行了客观定量的评价.最后通过VTK技术实现了边坡稳定性可视化平台的构建，为后续的边坡加固及灾害防治提供了可靠依据.

Abstract: A comprehensive assessment on rock slope stability was carried out by combining the key block theory with the fuzzy method. Based on typical slope of strip mine in Fushun， the physical and mechanical parameters were measured and a block identification system—GeoSMA-3D (Geotechnical Structure and Model Analysis-3D) was developed to identify the key blocks and to calculate the factors of safety. The assessment factors were detemined based on the characteristics of the spatial blocks. According to the information acquired， a fuzzy comprehensive assessment method based on AHP was applied to assess the stability of the slopes in an objective and quantitative way. Finally， an visualizaion plantform is established to visulize the terrain and total safety factors of the slope， which provides a reliable basis for disaster control and reinforcement on the slopes.

Key words: strip mine, rock slope, analytic hierarchy process, block theory, fuzzy evaluation
