地震作用下城市供水管网可靠性评估方法的研究
|
摘要
根据供水网络的连通性分析结果并结合管段间的逻辑关系建立可靠性结构函数,在此基础上对结构函数进行了不交化运算,并根据各个管段的地震可靠度计算出城市重点供水区域的可靠度。最后,结合可靠性理论,对供水网络各个管段的重要度进行了分析。文中通过算例说明了该方法的可行性和有效性。总之,这种方法为计算城市供水管网的地震可靠度提供了一种新思路,并有助于提高重点区域在地震作用下的供水安全性。
Based on the analysis of the connectivity of water supply network,the reliability structure function is established in accordance with the logical relationship between the pipe-sections.On the basis of this,a disjoint calculation is made on the structure function,and then the reliabilities of the key urban water supply areas are calculated with the seismic reliabilities of all the pipe-sections.At last,the importances of all the pipe-sections within the network concerned are analyzed according to the reliability theories.The feasibility and effectivity of the method are introduced through the actual calculation case,and it is demonstrated that the method can not only provide a new concept for the calculation of the seismic reliability for urban water supply network,but also be helpful for enhancing the safety of water supply under seismic effect within the key areas.
