摘　　要：通过引入弹模弱化系数 KE 和粘聚力弱化系数 Kc,建立了岩体强度和变形参数与其风化程度的联系。由于影响岩体风化程度的因素多而复杂且影响程度不同,特总结了四类 20 项主要影响因素,采用两级模糊综合评判方法对黄麦岭磷矿采场边坡岩体的风化程度进行研究,取得较满意的结果。By introducing soft coefficients of the elastic modulus and cohesion, the relationship between strength and deformation parameters and the weathering degree of rocks are established. Because the effects of weathering degree are complex and the affecting degrees are different, the weathering degree and the uses of the fuzzy mathematic method to estimate the rock weathering degree are summarized. The method was applied to an open pit mine slope with reasonable results.
