探讨了城市地下空间岩土体可利用性研究中需要考虑的工程地质因素,将地下空间按不同深度分为0～10m浅层区域、10～50 m中层区域和50 m以下深层区域,从而根据不同深度的工程特性对岩土体可利用性进行划分,并探讨了划分依据及意义。
The engineering geological factors to be considered in the study on the availability of geotechnical soils in urban underground space are discussed. According to different depths, the underground space is divided into 0 ~ 10m shallow area, 10 ~ 50m middle area and 50m deep area, Different depth of engineering characteristics of rock and soil availability of the division, and to explore the basis for division and significance.
