开发了一个基于计算机的模拟模型，以量化供水网络可能发生的地震破坏，并提出此类事件后的恢复策略。该模型的目的是产生概率地震事件，并确定设施的结构损坏。然后，该模型通过将其与水力分析求解器连接来数值量化系统随时间的恢复率。该模型旨在通过使用几个恢复方案进行敏感性分析，提出高超的恢复计划。所开发的模型被应用到一个实际的大都市自来水厂系统目前在韩国运行，并成功地建议了最有效的恢复方法（地震破坏），以尽量减少完整的恢复时间和暂停供水服务。预计所提出的模型可以被用来作为一个决策工具，以确定及时的系统恢复计划和恢复优先级的情况下，可能会发生在供水网络的实际地震灾害。
A computer-based simulation model was developed to quantify the seismic damage that may occur in water supply networks and to suggest restoration strategies after such events. The model was designed to produce probabilistic seismic events and determine the structural damage of facilities. Then, the model numerically quantifies the system restoration rate over time by connecting it with a hydraulic analysis solver. The model intends to propose superb restoration plans by performing sensitivity analyses using several restoration scenarios. The developed model was applied to an actual metropolitan waterworks system currently operating in South Korea and successfully suggested the most efficient restoration approaches (given seismic damage) to minimize the complete recovery time and suspension of water service. It is expected that the proposed model can be utilized as a decision-making tool to determine prompt system recovery plans and restoration priorities in the case of an actual seismic hazard that may occur in water supply networks.
