摘　　要：提出了一种新的围岩的稳定性评价方法———等效数值法,建立了基于等效数值方法的围岩稳定性评价新模型.该方法将样本指标值与围岩稳定性各指标分类标准对比来确定权重,客观性强,计算简捷.对5个典型的围岩作为评价样本进行了评价研究,并将得到的评价结果与模糊识别法、可拓方法与模糊可变集合工程方法结果进行比较.研究结果表明,等效数值法成功率高、客观性强,为围岩稳定性的评价研究提供了一条新思路.In this paper, a new stability evaluation method on surrounding rock mass by using equivalent numerical method is presented. The stability assessment model for the Surrounding Rock Mass based on an equivalent numerical method is established. 5 actual samples were used to verify the effectiveness of this method. Compared with Furry Pattern Reeoginition,extension method and engineering method of variable fuzzy set, equivalent numerical method has a practical performance in evaluating the stability of surrounding rock mass. This paper provides a new way for evaluation on stability of surrounding roek mass.
