Seismic Vulnerability Analysis of Water Pipeline in Wenchuan Earthquake

The seismic damage and loss of service of pipeline engineering may have great influence on the society, so the seismic research of pipeline engineering had always been highly valued. In this paper, the seismic damage characteristics of pipeline and vulnerability of water pipeline system in Wenchuan earthquake are analyzed, some revelations have been presented. The seismic capacity of pipeline engineering in some towns and cities was not adequate, the pipeline systems suffered great losses in Wenchuan Earthquake, and effective seismic countermeasures should be considered in design and construction of water pipeline system in order to improve this situation.
