摘　　要：为了解综合管廊的火灾风险问题,探究各风险因素之间的权重及作用机理,增强地下综合管廊的火灾风险管控能力,基于历年建筑火灾风险识别的相关文献,采用EFA建立了指标体系,通过调查问卷进行数据样本收集,运用结构方程模型对各火灾风险因素进行权重计算,对潜在影响因素进行深入分析。实证结果显示,建筑自身防火能力、人员防控能力、消防监管能力、火灾控制系统能力对管廊火灾风险控制具有正向作用。结果表明,正确选用管廊内装饰材料与设备是防火的关键,完善监管制度并提高相关人员安全素质是防火的重要举措。In order to understand the fire risk of utility tunnel,this paper explores the weight and mechanism of each risk factor,so as to enhance the fire risk control ability of underground utility tunnel.Firstly,based on the literatures related to building fire risk identification over the years,an index system was established by exploratory factor analysis method.Secondly,data samples were collected through questionnaires.Finally,the structural equation model is used to calculate the weight of each fire risk factor,and the potential influencing factors are deeply analyzed.The empirical results show that the fire prevention ability,personnel prevention and control ability,fire supervision ability and fire control system ability of the building have a positive effect on the fire risk control of the the tunnel.The results show that the correct selection of decorative materials and equipment the tunnel gallery is the key to fire prevention,and it is an important measure to perfect the supervision system and improve the safety quality of relevant personnel.
