Research on the Evaluation Indicator System of Urban Infrastructure Resilience

Urban infrastructure is the guarantee for cities to maintain normal socio-economic activities. Resilience assessment of infrastructure helps to ensure the safe operation of infrastructure. In view of the actual needs and important problems of urban safety at this stage, this study starts from the concept of resilience development and urban safety resilience, analyzes the characterization of safety resilience, and proposes a characterization model of urban infrastructure safety resilience. Based on the three basic elements of risk source, disaster bearing body and disaster reduction body, the framework of urban infrastructure safety resilience is constructed. This study analyzes and summarizes the main influencing parameters of the functional changes of infrastructure in each stage of resistance, adaptation and recovery, and establishes the indicator system of urban infrastructure safety resilience evaluation, which provides a reference for the evaluation of urban infrastructure safety resilience and urban safety improvement countermeasures.
