摘要:
震后,供水管网处于低压供水状态,使得管网中部分用户的水压和水量不能得到全部满足,导致管网部分节点的实际配水量小于需水量,为此,在传统的管网水力分析基础上考虑节点流量随水压的动态变化,进而求解管网节点实际流量和水压。为了比较传统的水力分析和考虑不同节点流量与节点压力的关系对水力分析结果的影响差异,对一实际管网进行了震后水力分析。结果表明,考虑节点流量随水压动态变化的水力分析能得到合理的节点压力和节点流量计算值。
Abstract:
After a strong earthquake,there are some cases where nodal pressure is not sufficient for supplying the required demand in the water supply network,and the flow of water is less than that of demand before the earthquake.An efficient approach for pressure-dependent demand analysis is developed to simulate the hydraulic states of the network for low pressure cases,which is an improvement of the conventional demand-driven model.Comparisons between the conventional demand-driven approach and the pressure-dependent approach are presented for a water distribution system.The pressure dependent demand analysis approach is proved to be efficient to analyze many conditions,in which the demand is function of pressure in the water supply network.
