关于地下空间重要的国家资源 开发利用问题的思考

从构成城市建筑物的发展历史看，21世纪是人类开发利用地下空间的世纪。地下空间是国家的重要资源。全球陆地地表被各类工程建筑物等占去1/6，随着工业化、商业化、城市化进程的加快，人地矛盾加剧，土地的承载力加重，充分开发利用地下空间资源是必然趋势。城市地下空间开发利用技术的发展趋势是综合化、分层化与深层化、城市交通地下化等，提出了把地下空间开发作为国策、纳入城乡规划的法制轨道及加强地下空间的开发技术岩土工程勘察技术、开挖技术和设计施工技术等建议。

Underground Space

The 21st century will be the century in which human beings will exploit the underground space in the perspective of the evolution history of urban building. The underground space is one of the important national resources. One-sixth of the land surface of the entire earth is occupied by various buildings. With industrialization, commercialization and urbanization, the contradiction between the population and the land will be aggravated, and the bearing capacity of the land will be overburdened. To fully exploit the underground resource will be the inevitable trend. The trend of the urban underground space exploitation technology will move toward integration, multi-layers and deeper into the ground with the urban traffic switched underground. It is suggested that the exploitation of the underground space be included in the urban planning as the national policy. Proposals on how to enhance the underground exploitation technology—geo-technical investigation, excavation technique and design and construction techniques are also put forward.
