【摘要】：研究城市关键基础设施体系在各类毁伤下的恢复能力评估方法。基于现有恢复力研究中考虑因素的不完整性,提出了"恢复程度"这一关键因素,同时构建了包含毁伤概率、毁伤后果、恢复速率和恢复程度4个主要因素在内的城市关键基础设施体系恢复力定量评估理论框架。在恢复力技术和组织两个维度分别设计体系性能时程响应函数,实现了恢复力在技术和组织双维度上的评估。在以江苏省连云港市区供水网络为例的案例研究中,依据所提出的评估框架构建体系恢复力评估仿真流程,对特定毁伤场景下的体系毁伤恢复力进行分析,得出关键基础设施体系毁伤恢复力在不同恢复条件下的变化规律。
[Abstract]:This paper studies the methods of evaluating the resilience of urban critical infrastructure system under various kinds of damage. Based on the incompleteness of the factors taken into account in the existing research of resilience, this paper puts forward the "degree of restoration" as a key factor. At the same time, the damage probability and the damage consequence are constructed. A theoretical framework for quantitative assessment of the resilience of urban critical infrastructure systems, which includes four main factors of restoration rate and degree of restoration, is proposed. The time-history response functions of system performance are designed in the two dimensions of resilience technology and organization. In the case study of the urban water supply network in Lianyungang, Jiangsu Province, the simulation process of resilience assessment is constructed according to the proposed evaluation framework. Based on the analysis of the damage resilience of the system under the specific damage scenario, the variation of the damage resilience of the key infrastructure system under different restoration conditions is obtained.
