In order to improve the ability of planning, design and health evaluation of infrastructure, such as power, urban traffic and water supply and drainage, and to reduce the urban global risk caused by its failure. Give an example of Chongqing, Wanzhou electric power infrastructure, use social network analysis (SNA) theory and method, build power infrastructure status and network planning respectively, propose the network health evaluation system composed of network complete index and so on, use the network calculation models such as density to assess the health of network topology and its operating state.
