摘要
危岩影响因素复杂,具有多因素、模糊性和不确定性.文中在危岩发育影响因素分析的基础上,运用层次分析模型,量化各影响因素的权值矩阵,并将该权值矩阵引入模糊综合评价,通过将层次分析法和模糊评价有机结合,提出了危岩危险度AHP-Fuzzy综合评价方法.通过工程应用,及同当前通行稳定性计算方法的对比分析表明,本文方法具有较好的可靠性,而且该方法使危岩危险度评价建立在部分定量、部分定性、易获得的指标之上,避免了传统方法对勘查质量、岩体参数的高要求.
The development of perilous rock has complicated, multi-factorial, fuzzy and uncertain characters. Based on analysis of perilous rock development factors, the weighting matrix of these factors is quantified using AHP model. And then the weighting matrix is introduced into fuzzy integrative estimate. By combining the AHP method with fuzzy theory, the AHP-Fuzzy method is presented for dangerous degree estimate of perilous rock. Compared to typical stability analysis method of perilous rock, the AHP-fuzzy method has preferable reliability in engineering applications. Besides, this method is based on partial quantitative, partial qualitative and facile parameters. The disadvantages of typical stability method are avoided which extremely depends on investigation quality and mechanics parameters of perilous rock.
