Research on the Vulnerability Risk Assessment of Water Supply Network under Earthquake

Abstract

The seismic vulnerability of water supply network system refers to the network after the quake affected degree of each node. Based on mutation progression method, water supply pipe network seismic vulnerability is analyzed. Position in network topology and node service features as factors, which influences the network vulnerability assessment indexes is determined. The vulnerability level of the network could then be evaluated using qualitative and quantitative methods. This approach is validated to be effective and appropriate through an application to a post earthquake analysis of a water supply network system.
