摘　　要：岩体结构性和非均质性决定力学参数c、φ是各个因素作用下一个综合值,同时由于影响因素繁多、机理复杂和工程地质条件的复杂性,c、φ具有很强的模糊性。影响岩体的力学性质的因素很多,这些因素本身就具有很强的模糊性。针对大冶铁矿采场边坡工程,根据边坡岩体所处工程地质环境,采用多级多因素模糊综合评价法区分不同因素对边坡影响,进而得到合理的力学参数。该方法简便易行,充分利用人们对岩体力学性质特征认识的经验积累,便于在工程中运用,具有较强的适用性。Mechanics parameters-c and φ are comprehensive value due to the rock＇s structure and anisotropy. Meanwhile c and φ will become fuzzier owing to so many influencing factors, the complexity of their formation mechanism and geological conditions. Based on the geological environment for the slope engineering in Daye Iron Mine, the influence of each factor on the slope is analyzed by a multistage fuzzy comprehensive evaluation, and reasonable rock mass mechanics parameters are obtained. Such fuzzy comprehensive evaluation is not only easy for operation, but also make full use of people＇ s experience on rock mass mechanics. It has proved to be applicable in many cases.
