考虑震后服务功能时变过程，是供水管网抗震韧性分析的重要特征。管网震后服务功能变化不仅受管道结构物理状态影响，还受到管网调节设施状态的影响。本项目拟在生命线工程防灾与给排水系统的交叉领域，研究供水管网抗震韧性分析方法，进而提出震前设防提升和震后恢复方案。（1）构建包含调控设施影响的离散事件动态系统模型，分析供水管网震后功能时变过程，揭示“参数变量—管网物理/运行状态—服务功能—抗震韧性”的传递规律（正问题）。（2）考虑调节设施的运行状态变化，建立地震破坏管道修复次序和维修队伍指派的优化模型，明确管网物理/运行状态、可用修复资源与震后最优恢复策略的对应关系。（3）将供水管网抗震韧性目标分解为韧性特征指标（抵抗、适应、恢复能力）需求，建立供水管网抗震整体韧性分层提升优化模型，明确“抗震韧性—参数变量”的映射关系（反问题）。本项目研究有助于揭示供水管网抗震韧性机理，提升供水管网震后供水保障能力。

The time-varying process of the post-earthquake performance is an important feature of the earthquake resilience analysis of water supply network. After an earthquake, the performance change of water supply network is not only affected by the physical state of the damaged pipelines, but also affected by the state of the pipe network controlling facilities. This project intends to study the earthquake resilience mechanism of water supply pipe network in the cross field of disaster prevention of lifelines and water supply system, and then propose the pre-earthquake fortification scheme and post-earthquake recovery strategy. (1) Construct a discrete event dynamic system model including the influence of controlling facilities to analyze the post-earthquake performance time-varying process of water supply network. Then, reveal the transmission law between "parameters /variables - pipe network physic/operation states - service performance - earthquake resilience" .(2) Considering the state changes of the controlling facilities, the optimal model of the recovery sequence of earthquake damaged pipelines and the assignment of the repair team is established. Then, the corresponding relations between the physical/operating state of the pipeline network, available repair resources and the optimal post-earthquake recovery strategy is clarified. (3) Decompose the earthquake resilience target into the demands of characteristic indexes of resilience (i.e. resistance, adaptation and recovery) of water supply network, then establish an optimization model of overall earthquake stratified improvement of water supply network, and finally define the mapping relation of "earthquake resilience target- parameter/variable design". The research of this project is helpful to reveal the earthquake resilience mechanism and improve the post-earthquake water supply security of the water supply network.
