摘　　要：考虑到传统方法在确定爆管影响因素权重中的局限性,引入了模糊层次分析法(FAHP),建立了爆管因素评价模型,并基于FAHP法中模糊一致矩阵同权重的关系,建立方程并求得各因素的权重。最后以北方某市爆管影响因素分析为例,验证了用FAHP法确定爆管因素权重的可行性,从而可确定各因素对爆管的实际影响程度,为后期对爆管的多因素综合分析奠定了基础。Considering the limitations of traditional methods in determining weights of the influence factors of water pipe breaks, the model for evaluating the influence factors of water pipe breaks was set up by introducing fuzzy analytical hierarchy process （FAHP）. According to the relationship between fuzzy consistent matrix and weight in the FAHP, a set of equations were established to obtain weights of factors. Taking the analysis of influence factors of water pipe breaks in a northern city for example, the feasibility of determining weights of the influence factors of water pipe breaks by the FAHP was verified, thus solving the actual influence degree （that is the contribution to water pipe breaks） of each factor in water pipe breaks and providing the premise for a multi-factor comprehensive analysis of water pipe breaks in the further study.
