从城市地下空间开发利用的经验及合肥城市化带来的问题出发,阐述了合肥城市地下空间开发的紧迫性和可行性,分析了合肥市地下空间开发利用的现状,结合合肥市工程地质条件及勘察资料,对地下空间开发中可能遇到的膨胀土、软土等特殊土问题进行了分析;并通过借鉴国内其他大城市的地下空间发展与规划经验,提出了合肥市地下空间开发中应注意的地下空间规划、地下空间管理、人防工程以及与已建的地下空间关系等四个问题,为合肥城市地下空间的合理开发利用与可持续发展提供有益参考。
Based on the experience of development and utilization of urban underground space and the problems brought about by the urbanization in Hefei, the necessity and feasibility of the development of urban underground space in Hefei were expounded. The status quo of the development and utilization of underground space in Hefei was analyzed. Combining with the engineering geological conditions in Hefei and Survey data, and analyze the problems of special soil such as expansive soil and soft soil that may be encountered in the development of underground space; and draw lessons from the experience of underground space development and planning in other big cities in China, we put forward that we should pay attention to the development of underground space in Hefei Of the underground space planning, underground space management, civil air defense projects and the relationship with the underground space has four issues for the rational development and utilization of Hefei city underground space and provide a useful reference for sustainable development.
