【摘要】 依据可变模糊集理论,提出了围岩稳定性的可变模糊工程综合评价方法,它不仅可确定影响围岩稳定性的各个指标对各级别标准值区间的相对隶属度,而且在多指标综合评价中,可变换模型的参数,提高评价结果的可靠度,从而可合理地分析围岩的稳定性和确定其所处的级别.该方法应用于黄河大柳树水电站导流洞围岩稳定性分析,取得了较好的效果.与模糊物元评价方法的结果进行比较与分析,进一步验证了该方法的合理性.更多还原

【Abstract】 Based on the theory of variable fuzzy set,a method of variable fuzzy evaluation for analysis of surrounding rock stability is proposed,which can identify the relative membership degree between sample index and standard-value interval of each level index,and which can improve reliability of evaluation result in multi-index synthetic evaluation by varying model and its parameters,and which can reasonably analyze the stability of surrounding rock and determine its level.The method is demonstrated by application to diversion tunnel of the Daliushu Hydro Project,which get better results.Evaluation result of comparison of this method with fuzzy matter-element evaluation method proves that variable fuzzy evaluation method is reasonable.更多还原
