兼顾防灾的高密度地区地下空间规划策略探讨

随着我国城市化不断推进,城市在建设开发中逐渐成型局部高密度状态,在全球化灾害多发的环境下,城市高密度地区的易损性显著,应充分利用其立体化空间加强防灾减灾建设。地下空间具备先天的防灾特性,可以针对不同灾害中发挥相应的防灾作用,并与地面防灾空间协同构建立体化的防灾空间体系。根据地下空间在城市高密度地区的防灾角色与定位,提出了在地下空间建设中兼顾防灾的规划思路,通过分析适合防灾用途的地下空间特点,对其空间和功能要求进行了研判,并进一步提出了引导方法和规划策略,对城市高密度地区地下防灾空间规划建设进行了探索。

Discussion on the Strategy of Underground Space Planning for Disaster Prevention in Urban High-density Area

With the development of urbanization in China, the local high density state is gradually formed in the construction of cities, and the fragility of urban high-density areas is obvious in the context of the multiple disasters of globalization. It should be strengthened that construction of disaster prevention and mitigation by using its stereoscopic space. Combined with the innate disaster prevention characteristics of underground space, this paper analyzes the disaster prevention function in different disasters, and probes into the synergetic relationship between underground and ground disaster prevention space. By studying the role and location of underground space in disaster prevention space system, the contents of underground disaster prevention space are defined, the requirements of suitable disaster prevention use in underground space is analyzed, and the control guidance method and planning strategy is further put forward.
