城市电力电缆隧道消防安全评估研究

Study on Fire Safety Evaluation of Urban Power Cable Tunnels

电力电缆隧道是未来城市电网建设的一个重要发展方向。为对城市电缆隧道的消防安全水平进行评价,构建了城市电力电缆隧道消防安全评估指标体系,共包含40个评价因素,涉及电缆的燃烧属性、电缆的运行状态、电缆隧道环境特征和电缆隧道消防配置4个方面;然后,利用模糊层次分析法对某城市地下电力电缆隧道的火灾风险进行实例研究,结果表明该评价体系具有一定的科学性,可为提升城市电力电缆隧道的消防安全水平提供建议。

Urban cable tunnels are the significant direction of the power grid construction in the future.In order to evaluate the fire safety level of urban cable tunnels,the index system of fire safety assessment for urban power cable tunnels is constructed.The index system includes 40 evaluation factors,which involve in four aspects:the fire attribute of cable,the operation state of cable,and the environmental characteristics of cable tunnels and the fire protection equipment of cable tunnels.Then,the fuzzy analytic hierarchy process is used to conduct an empirical study on the fire risk of urban cable tunnels.The results show that the fire safety assessment index system we developed is scientific and can bring the necessary help to enhance the fire safety level of urban power cable tunnels.
