摘要
基础设施系统是城市运行的根本,对城市的生产生活起着重要的作用,灾害事件频发对城市基础设施造成了极大的损失。近年来,因极端天气造成的城市灾害愈发频繁,对城市基础设施系统带来了巨大的压力,为了面对日益严重的自然灾害的压力,必须量化城市应对灾害的恢复力。韧性是一个包含准备、响应以及恢复的过程,该文以恢复力矩阵框架为基础,结合PSR模型构建用于评估基础设施恢复力的方法。该方法总结了多阶段恢复过程的状态和优先事项,可以用于特定的场景选择适合的指标,将其应用于“7·20”郑州特大暴雨灾害事件,基于灾后新闻发布会公布的灾情数据,选择了与当地相关的恢复评估指标,以探究本次灾害过程中的基础设施恢复力,这有助于对当地灾害恢复以及备灾进行补充。
The frequent occurrence of disasters causes great losses to cities.Infrastructure systems are fundamental to urban operation and play an important role in the productivity of cities.However the frequent occurence of disasters causes great losses to city infrastructure systems.Urban disasters caused by extreme weather have become more frequent in recent years,placing tremendous pressure on infrastructure systems.It is critical to quantify the resilience of cities in order to face the pressures of increasing natural disasters.Resilience is a process that encompasses preparation,response,and recovery.A resilience modeling approach combining the resilience matrix approach with the press-state-response model is presented to quantify the resilience of infrastructure systems after extreme events.The method summarizes the states and priorities of the multi-stage recovery process are summarized,which can be used to select suitable indicators for specific scenarios.Based on data released at the“7·20”Zhengzhou torrential rain disaster press conferences,we select relevant indicators to explore the infrastructure resilience in this disaster,which helps to supplement local disaster recovery and preparedness.
