城市供水管网基于性态的抗震防灾规划设计与控制方法研究

The performance-based seismic design theory including the considerations of “Graded Protection”, “Important Customer Security” and “Optimum Layout” will be proposed for urban water distribution system (WDS). In this way, the traditional seismic design objective for improving seismic capacity of WDS pipelines can be transformed into guarantee the post-earthquake emergency serviceability as WDS network performance objective, which is an feasible measure to avoid the important customer nodes out of service after the earthquake and to let the relief supplies play its role effectively after the earthquake for reducing seismic losses. Therefore, the problem has become the current hot research topic in the field of lifeline disaster prevention and mitigation..Through the combination of theoretical analysis, numerical and experimental simulation, this program will put its research emphasis on the performance-based seismic prevention planning and design and control method for WDS. The program is mainly intended to: (1) analyze the internal relations among the seismic damage of pipeline structure, the seismic capacity of WDS network and post-earthquake emergency serviceability so as to establish the fortification objectives，performance indicators and design parameters of performance-based seismic design for WDS; (2) establish the models and design methods of performance-based seismic prevention planning and design, taking full account of the temporal and spatial variation of the topological structure of WDS network and emergency water supply demand; (3) put forward the emergency service security theory of WDS under different recovery strategies with consideration of emergency water supply demand variation at different post-earthquake periods. This program will provide theoretical foundations for the extent of the earthquake disaster prevention planning and design method for urban WDS.

基于性态的抗震设计理论进行城市供水管网“分级设防、重点保障、优化布局”，实现从传统的管网单元抗震能力提升到以震后应急支撑服务功能为性态目标的转变，是避免供水管网重要用户节点震后失效，有效发挥其应急救灾保障作用并减灾地震灾害损失的重要手段，也是当前生命线工程抗震防灾领域中的研究热点。.项目拟通过理论分析、数值仿真与实验模拟相结合的方法，解决供水管网基于性态的抗震防灾规划设计与控制理论的相关科学难题。主要研究：（1）解析管道单元结构破坏、管网抗震能力与震后应急服务功能三者之间的内在关联，构建基于性态的供水管网抗震设防目标、性态指标和设计参数；（2）考虑震后管网拓扑结构和应急供水需求的时空变化，建立基于性态的管网抗震防灾规划设计方法与模型；（3）考虑震后不同时序阶段应急供水需求差异，提出不同恢复策略下基于性态的供水管网应急服务功能保障理论，为城市供水管网抗震防灾规划设计方法的拓展提供理论依据。
