摘要
随着城市发展,旧城区交通流量不断增加,下穿隧道成为缓解交通压力的一种有效方法.位于我国西南地区的旧城区因地形高差起伏较大、现状市政供水管道压力分布不均匀,导致常规计算难以判断隧道内各点的消防供水压力.文章以四川省宜宾市某隧道工程为例,采用EPANET水力模型对隧道消防供水管网进行模拟研究,分析 3 种消防水源不同组合工况下消火栓系统的运行压力.研究表明,消防水源采用对角线的布置方式更为合理,使得管网运行压力更均匀,消防供水也更加安全.通过EPANET进行水力模拟,可更加准确、直观地判断不同水源工况下管网系统的运行状况,为复杂型隧道消防系统设计提供理论依据.
Abstract
With the development of the city,the traffic flow in the old urban area is increasing,and underpass tunnel has become an effective method to relieve the traffic pressure.The old urban area in Southwest China is difficult to judge the fire water supply pressure at each point in the tunnel by conventional calculation due to the large topographic elevation difference and uneven pressure distribution of the current municipal water supply pipeline.Taking a tunnel project in Yibin,Sichuan as an example,this paper uses EPANET hydraulic model to simulate the tunnel fire water supply network,and analyzes the operating pressure of the fire hydrant system under different combination conditions of three kinds of fire water sources.The research shows that the diagonal layout of fire water source is more reasonable,which makes the operation pressure of the pipe network more uniform and the fire water supply safer.The hydraulic simulation by EPANET can more accurately and intuitively judge the operation status of pipe network system under different water source conditions,and provide a theoretical basis for the design of complex tunnel fire protection system.
