摘要
城市供水管网的抗震研究能够服务于供水管网的规划、设计和改造。以沈阳市供水管网系统为背景,介绍了一类求解大型供水网络节点及系统功能可靠度的方法。对沈阳市主干供水网络进行了抗震功能可靠性分析。研究结果证明,建议方法是合理评价供水管网地震后工作性能的工具,可以为大型供水管网的抗震可靠度分析及抗震设计服务提供基础。
A hydraulic analysis program of the water supply system in earthquakes is introduced based upon the hydraulic analysis method in a normal state.On the basis of the seismic response analysis of buried pipelines,a new leakage model is presented in this article.This model is applied to the analysis of the water supply system with the first-order reliability method(FORM),a new analysis method of the capability reliability of a water supply system is suggested.This method is applied to the seismic hydraulic anal...
