地铁车站火灾风险模糊层次综合评估模型与应用分析

Comprehensive Fuzzy AHP Model for Fire Risk Prediction in Subway Station and Its Application Analysis

地铁车站由于其结构的特殊性,一旦发生火灾,往往会造成重大的人员伤亡和财产损失。针对地铁车站火灾风险评价的研究具有重要意义。针对火灾风险等级各变量分析的基础上,构建了火灾风险等级评价指标体系和递阶层次评价结构,并建立抉择评判集以量化所提出的评价指标,对广西南宁地铁1号线工程实例进行火灾风险等级模糊层次综合评判。研究结果表明:通过采用模糊层次综合评判法对地铁车站火灾风险进行评价,能够对其进行多层次的分析研究,且建立的综合评价指标体系能够反映各类因子对地铁车站火灾风险的影响。

Due to the particularity of its structure,once a fire occurs,the subway stations often cause significant casualties and property losses. It is of great significance to study the fire risk assessment of subway stations.Based on the variable analysis of the fire risk grade,this paper establishes an evaluation index system and a hierarchical evaluation structure for the fire risk grade,and also proposes the choice evaluation set to quantify the proposed evaluation index. The project of Metro Line 1 in Nanning,Guangxi Province is taken as an engineering case study to implement the Fuzzy Comprehensive AHP evaluation of fire risk level. The research results show that the fuzzy comprehensive AHP evaluation method is able to comprehensively evaluate the risk grade of station fire through the establishment of comprehensive evaluation index system,which is also able to comprehensively consider the factors that affect the risk grade of the subway station fire.
