Seismic vulnerability model of urban water supply networks based on population and GDP in southwest China
The water supply network is an important component of urban lifeline engineering,a scientific and reasonable seismic vulnerability model for the water supply network is one of the key scientific issues for implementing disaster risk investigation and key hidden danger investigation projects.Especially for large-scale water supply network seismic disaster risk assessment,it is necessary to clarify the seismic vulnerability model of the water supply network zoning and classification as support.However,due to the complexity of the development process of the water supply network,many towns are still unable to provide accurate and effective basic data of the network for effective seismic vulnerability assessment.In order to establish the seismic vulnerability model of the urban water supply network without the basic data of the pipe network in southwest China,based on the established seismic vulnerability model of the urban water supply network with the basic data of the pipe network,the polynomial fitting method is used to give the relationship model between the scale and seismic vulnerability category of the urban water supply network with the basic data of the pipe network,the urban population and GDP.Then the pipe network scale and seismic vulnerability category can be estimated according to the urban population and GDP data without the basic data of the pipe network.It has laid the foundation for comprehensively carrying out the seismic disaster risk assessment of the large-scale water supply networks.
