摘　　要：本文利用模糊信息分析法对兰州市的大面积典型斜坡稳定性进行了计算。文中以岩性、斜坡坡度、斜坡高度、年平均降雨量、地震动参数及斜坡结构类型等数种参数作为评价指标。最后参照本计算结果并结合工程地质比拟法求出了兰州市其它斜坡的稳定性,编制了1∶5万50年及100年10％超越概率的地震动参数影响下的兰州市斜坡稳定性分区图,为兰州市抗震防灾规划提供了重要依据。In this paper, the authors have studied the stability of typical slopes in part of Lanzhou ,Gansu Province by using the fuzzy information analysis method. The evaluation elements are the nature of loess, the inclination of slope, the height of slope, the mean value of annual rainfall, the parameter of ground motion, the type of the structure of slope. Besides, based on engineering geological comparisons, the authors havedis-cussed the stability of other slopes in Lanzhou,and under the influence of 10% extra-probability of the parameter of ground motion, during 50 years and 100 years edited a distribution map of the slope stability in Lanzhou, 1 : 50000 in scale. It has provided important data for the planning of Lanzhou city and for the prevention of earthquake hazards there.
