城市地下空间恢复韧性发展策略研究
Development Strategy for Recovery Resilience of Urban Underground Space
防灾减灾理念及其运用在城市地下空间发展过程中发挥了一定的安全保障作用,但在自然风险和工程安全风险交织的背景下,无法全面满足城市地下空间未来发展需求;转向以“适灾”为导向的韧性防灾减灾理念,重视城市地下空间的灾后恢复韧性,成为未来发展亟需。本文分析了恢复韧性的内涵和影响因素,从工程、非工程角度阐述了国内外恢复韧性相关研究;重点从结构体系、评价方法、管理机制、空间规划、应急预案等方面,剖析了我国城市地下空间韧性发展现状。研究提出了“三阶段+评价体系”的城市地下空间恢复韧性发展策略,将灾后恢复过程划分为应急救援、恢复重建、规划适应三阶段,分别给出各阶段的恢复目标并为城市地下空间恢复韧性评价体系建设提供依据。研究建议,健全城市地下空间管理规章与应急预案,提高城市地下空间韧性规划水平,推动城市地下空间管理智能化,以促进城市地下空间恢复过程的有序与高效。
The concept of disaster prevention and mitigation is vital for the safe development of urban underground space. Considering the coexistence of natural and engineering safety risks, the concept needs to be improved for further development of the urban underground space, and it is imperative to follow a disaster-adaptation-oriented concept that emphasizes post-disaster recovery resilience of the urban underground space. This study analyzes the implications and influencing factors of recovery resilience and summarizes the research on recovery resilience from the engineering and non-engineering perspectives. Moreover, the development status of recovery resilience research is analyzed from the aspects of structural system, evaluation method, management mechanism, space planning, and emergency plan. On this basis, a strategy that consists of three stages and an evaluation system is proposed; it categorizes post-disaster recovery into three stages—emergency rescue, recovery, and plan adaptation—and proposes recovery goals for each stage, providing a basis for the establishment of a recovery resilience evaluation system for the urban underground space. Furthermore, we suggest that the management regulations and emergency plans of the urban underground space should be optimized, the resilience planning improved, and intelligent management promoted, thereby realizing the orderliness and high efficiency of urban underground space recovery.
