城市地下空间开发利用问题的探讨

城市地下空间开发利用是人类社会发展和需求的必然趋势。论文以重庆市城市地下空间开发利用为例，针对重庆市遍布城市的地下人防工程、城市周边众多即将废弃的矿井和主城区地下较坚硬岩层的特点，结合国内外地下工程和矿山地下工程开发利用的成功经验，分析了城市地下空间开发的技术问题，主要包括地下空间开挖及围岩坍塌类型、地下空间围岩坍塌的诱因、地下工程围岩破坏控制技术；同时，探讨了城市地下空间利用的问题，主要包括地下人防工程，地下公共设施、地下运输线、地下街建设、共同沟建设；指出了城市大深度地下空间可开发性的优点；提出了重庆市地下空间开发利用的建议。

Discussion about Development and Utilization of Underground Space In Mountain City

With the development of society and human requirement, it is an inevitable tendency to develop and utilize the underground space in the city. Taking the development and utilization of underground space in Chongqing as an example, thinking about the great air-raid shelter resource, the abrogating mine in suburban, hard rock under the city, combining the internal and external successful experience of developing and utilizing the mineral underground space and large deep underground space, the skillful problems are analyzed including skills about digging underground space, the type of roof rocks collapse, the inducing factors about roof rocks collapse and the skills to control the collapse of roof rocks. At the same time the utilization of underground space is discussed, including air-raid shelter, public installation, transportation lines, construction of the underground street and construction of common tunnel. The advantage to develop the deep underground space is analyzed and some advices about how to develop the underground space in Chongqing are given.
