Abstract:: In order to establish the seismic vulnerability model of various water supply lines based on continuous ground motion parameters,we firstly assume that the number of earthquake damage of water supply lines meets Poisson distribution,then we use the empirical statistical model of seismic damage rate of water supply and the classification standard of pipeline damage grade,to put forward the seismic vulnerability matrix of water supply lines of different materials.We obtain the seismic vulnerability curves of six kinds of water supply lines based on PGA by fitting the two-parameter lognormal distribution function.The results lay a foundation for the comprehensive analysis of the loss rate of the whole water supply network in future,and provide support for the analysis of the seismic loss rate of the water supply network in the seismic insurance of water supply facilities.
