摘要
研究地震导致渗漏的供水管网的水力特性,考虑节点流量随节点水压的动态变化,构建地震导致渗漏的供水管网水力模型.基于EPANET计算管网节点实际流量和水压,评价供水管网水力特性.案例分析表明,构建的模型和提出的水力计算方法是可行的,为城市供水管网抗震防灾管理提供借鉴.
In order to study the hydraulic features of leaky water distribution system caused by earthquake,the nodal traffic dynamically variation by water pressure is considered and the hydraulic leakage model is built based on the hydraulic features of water supply network leakage. Combining with EPANET,the nodal traffic and nodal water heads can be obtained and the service performance of the water supply network can be evaluated. The example results of water supply network indicate that it is feasible for the hydraulic leakage model and the hydraulic computation method to apply to practice in a possible earthquake reasonably,which provide the reference for the earthquake mitigation management of practical water supply network.
