摘　　要：供水管道的地震易损性评估模型,可以实现管道震前和震后快速高效的震害评估与控制。文章首先介绍了5种与管道易损性模型相关的地震动参数,并对各类参数进行了对比分析;随后,以时间为主线,列出了供水管道地震易损性评估模型,并对各类模型进行了评述和比较。同时,也介绍了基于管网震后功能的地震易损性模型。研究结果表明:在对供水管网进行震害预测和评估时,应根据已知地震动参数条件和工作要求,选择合适的评估模型,兼顾考虑震后管网破坏处数和输水功能。最后,展望了供水管道地震易损性的研究前景。The seismic vulnerability assessment model of water supply pipeline can achieve rapid and efficient assessment and control of seismic damage before and after earthquakes. The five kinds of ground motion parameters related to pipeline vulnerability model are introduced firstly in this paper,and various parameters are compares and analyzes. Then,the seismic vulnerability assessment models are listed by taking time as the main line,and the various models are commented and compared. The seismic vulnerability model based on the post-earthquake function of pipeline network is also introduced at the same time. When predicting and evaluating the seismic damage of the water supply network,the appropriate evaluation model should be selected according to the known ground motion parameters and work requirements,taking into account the proportion of leaks and breaks and water transfer functions of pipeline network after earthquakes. Finally,the future researches on seismic vulnerability of water supply pipeline are prospected.
