摘　　要：根据露天矿边坡的特点,用梯形模糊数表示影响和制约边坡稳定性影响因子的各主要因素指标,运用模糊多属性Buckley决策的方法,确定方案-属性之间的模糊指标值和属性-属性之间的相对重要程度模糊权值,计算各方案的模糊效用值及其隶属函数,并对其比较、排序,从而确定对边坡稳定影响因子的重要程度,为实际工程设计、施工和管理提供了科学的决策依据.In accordance with the slope characteristics of open-pit, the primary factors affecting the slope stability are expressed in trapezoid fuzzy numbers. An approach to handling fuzzy weighting, the fuzzy utility function of every scheme is calculated by using FMADM Buckley to set decision making fuzzy utility value and the function. By comparison and ranking of fuzzy utility value, to determine the importance of every affecting factors for the slope stability, the study may provide a comprehensive, reasonable and scientific basis for engineering design, construction and control of open-pit.
