The seismic disasters features and behavior mechanisms of the buriedwater supply pipeline are analyzed by synthesis and the breakage of thepipe joints caused by seismic wave propagation as main disasters mode isled into. The soil-pipe interaction, and the soil-pipe slippage arediscussed. Statistical experience method resulted from earthquakeinvestigations and theoretical methods based on reliability theory areintroduced. The reliability of buried pipeline is researched. The methodfor estimate connective reliability of network by means of Monte Carlesimulation technique and Breadth First Search method is introduced. Theconnective reliability of water supply pipe network is researched.

本文综合分析了地下供水管道的地震破坏特征和反应机理，引入了以接头破坏作为主要的破坏模式，并探讨了管土间的相互作用和滑移作用等问题；介绍了根据震害调查数据回归的统计经验法和基于可靠性理论的理论分析法，对地下管道的可靠性进行了研究；介绍了利用蒙特卡罗法和网络图论中的广度优先搜索法判定网络连通可靠度的方法，对供水管网的连通可靠性进行了研究；考虑到震害预测方法中的许多参数是随时间变化的，应用灰色理论和概率论，建立了基于GIS 的供水管网动态震害预测模型。
