随着经济水平,城市化水平和人口的不断提高,地面用地紧张,尘世粗放式发展与城市集约式发展思路不符合。地上立交桥,天桥等虽然有效解决城市交通拥堵问题,但是天桥下面的空间利用率不高,同样造成土地浪费。为了实现城市的地上,地面,地下三维式发展,城市地下空间开发利用规模不断扩大。文章着重介绍了现代城市地下空间开发利用的必要性原因和优势。
With the economic level, the level of urbanization and the continuous improvement of population, land use is tense, and the earthly extensive development does not conform to the idea of urban intensive development. Above ground overpasses, overpasses, etc., although effectively solve the problem of urban traffic congestion, space utilization under the flyover is not high, also resulting in land waste. In order to realize the three-dimensional development of the ground, ground and underground of the city, the scale of urban underground space development and utilization is constantly expanding. The paper emphatically introduces the necessary reasons and advantages of the development and utilization of underground space in modern cities.
