中文摘要: 采用野外调查与室内实验相结合的方法,以四川汉源县二蛮山作为研究对象,通过对滑坡发生的环境条件、发育特征和机理进行分析,选取了滑坡体特征、地质构造、高程、坡向、坡度、地震、降雨等因素作为研究分析变量,将GIS与模糊数学评价方法相结合,开发滑坡稳定性评价插件,对研究区域进行危险性区划,尽量避免易发生地质灾害的区域,减小人员伤亡和财产损失.研究结果表明,滑坡的发生区域主要集中在高程1600 m左右、坡度30°—50°地段,随着高度和坡度的增大,发生滑坡的可能性也逐渐增加.

Abstract:In this paper, the method of theoretical knowledge, field surveys and laboratory experiments were used to analyze the environmental conditions, development characteristics and mechanism of the Ermanshan landslide in Hanyuan County, selecting the characters of landslide, geological structure, elevation, aspect, slope, earthquake, rainfall and other factors as analysis variables. We combine GIS with fuzzy mathematical evaluation method, develop the landslide stability evaluation plug-in, and then divide the risk regionalization of study area, in order to avoid occurrence of geological hazards in the area, reduce casualties and property losses. The results show that the landslide areas are mainly concentrated on the elevation at about 1600 m and 30° to 50° slope area. With the increase of height and slope, the possibility of landslides is raised.
