摘要 为评价岩质边坡稳定性,引入功效系数法的基本理论,在综合考虑影响边坡稳定性影响因子的基础上,选取七个具有代表性的影响因子构建边坡稳定性评价指标体系,根据既定体系确定相应的评价标准,建立了一种新的边坡稳定性评价模型。利用四个具有代表性的边坡样本对所建模型进行验证,评价结果与边坡实际稳定性等级基本一致,且与理想点法和可拓方法得到的边坡稳定性评价结果相近,证明了该方法评价边坡稳定性可行且准确性较高。 In order to evaluate the stability of rock slope,a model based efficacy coefficient method has been established to evaluate risk degree of slope stability.Seven assessment indexes were considered in the process of safety evaluation of slope stability.Safety evaluation grade and standard were given with the chosen assessment indicators.The model is tested by a series of slope sample.The obtained results are consistent with practical classification of slope stability and the results of idea point method and extensional method.So,it is shown that the efficacy coefficient method used to classify the slope stability is reasonable and effective.
