摘要
基于模糊物元理论,选择合理的岩石稳定性评价指标,通过隶属度计算,建立了岩石稳定性评价的模糊物元模型。为避免权重确定的主观性,采用求和归一法来确定评价指标的综合权重,最后根据关联度计算结果及最大关联度原则,实现了对谦比西铜矿井下围岩稳定性等级的多指标综合评判。结果表明:采用模糊物元理论进行岩石稳定性评价是有效可行的,为岩体稳定性评价提供了一条新的思路。
Based on the fuzzy matter-element theory,a reasonable evaluation index of rock stability is chosen,and the fuzzy matter-element model of rock stability is finally built through the calculation of membership, in order to avoid the sub- jectivity of weight determination, the sum normalization method is adopted to determine the comprehensive weight of evalua- tion index, and then according to the calculating result of membership and the principle of maximum correlation degree, the multi-index comprehensive evaluation of stability grades for underground surrounding rock of Chambishi Copper Mine is re- alized. The results show that it is effective and feasible to evaluate the rock stability with fuzzy matter-element theory, and what＇s more,it offers a new thought to do this.
