ANP-Based Disaster Persistence Evaluation System of Urban Underground Infrastructure from the Perspective of Time Evolution

Enhancing the disaster prevention capacity of cities has emerged as a significant concern in current urban development. Given the growing emphasis on Urban Underground Space (UUS) development, it holds immense importance to accurately assess the disaster resilience of Urban Underground Infrastructure (UUI) and its development trend for a comprehensive understanding of urban disaster prevention capabilities. This research paper introduces the concept of disaster persistence to elucidate the ability of facilities to sustain their operational functionality amidst disruptive disasters. Based on disaster theory, the factors influencing UUI disaster persistence to three critical disasters, namely earthquakes, fires, and urban flooding, are identified. Accounting for the interplay among these factors, an Analytic Network Process (ANP) network structure model of influencing factors is formulated. From the perspective of time evolution, considering the construction condition of facilities, surrounding natural conditions, and governmental management, a regional UUI disaster resilience evaluation framework is proposed to reflect dynamic changes over time. It is anticipated that this study will enhance public comprehension of the disaster prevention value associated with UUS, while concurrently offering technical support for future urban planning and design endeavors.
