摘　　要：近年来露天矿边坡引起的岩土工程风险问题越来越严重.基于对露天矿边坡灾变机理的研究,通过分析工程地质环境和现场勘察资料,选取坡度、高程、地质岩性、地下水位、地质构造为评价因子,结合层次分析法,利用地理信息系统(GIS)对露天矿边坡的地质灾害进行危险性等级划分.通过危险等级区划图,确定出边坡不稳定区域面积占总面积的31%,需特别注意,应采取加固监测措施,避免灾害发生.In recent years, geotechnical engineering slope become more and more serious. Based on the risk problems caused by open-pit minestudy of the slope disaster mechanism and analysis of engineering geological environment and field survey data, slope, elevation, geolog- ical lithology, underground water level,geological structure are selected as evaluation factors, in combination with Analytic Hierarchy Process, by using Geographic Information System （GIS）to grade the risk of slope geological disaster. Through the analysis of danger degree zoning map,and statistical landslide prone, high risk and the risk area accounted for 31 ~ of total area, special attention should be paid, and strengthening monitoring, measures should be taken to avoid disasters.
