Urban water supply network system is an important part of the lifeline engineering . In recent years, many destructive earthquakes , the destruction of the city water supply system is not only affecting the smooth progress of the relief work , but due to secondary disasters directly caused serious casualties and economic losses . China 's urban water supply pipe network system , most did not go through the regular seismic design . In this paper, based on the needs of urban earthquake disaster prevention work , based on research at home and abroad , combined with engineering instance , to make a more comprehensive system of research on the seismic reliability analysis of the problem of urban water supply pipe network system . The main work of this paper are as follows: 1. Domestic and international historical damage survey results , and comprehensive analysis of the water supply pipeline damage characteristics and reaction mechanism . Improved seismic code method (GB50032-2003) in the seismic response of buried pipeline analysis , finite element model with ANSYS finite element software and compared with the results before and after the improvement of the seismic code method . The preparation of a water supply pipeline seismic code method based on improved seismic response calculation procedures . Results based on the analysis of the seismic response of the water supply pipes , the establishment of a water supply pipeline seismic reliability analysis model . The preparation of the corresponding computer program and engineering instance , to assess the the pipeline seismic reliability of the water supply network system . Monte-Carlo - based simulation and graph theory using Matlab language preparation of the water-supply systems connectivity reliability analysis program . With an example, to assess the reliability of the water supply network system connectivity to verify the effectiveness of the program . After the earthquake on the use of water-supply systems function hydraulic analysis of water-supply systems after the earthquake foreshocks to node freely water pressure for the evaluation of functional reliability analysis . Self Matlab program and with engineering examples , the functional reliability of the water supply network system .
