上海深层地下空间开发地质环境条件及适宜性评价

Geo-environmental condition and feasibility assessment of the deep underground space in Shanghai city

随着上海市浅部和中部地下空间资源的不断消耗,地下空间开发利用将向深层发展和延伸。本文在对上海中心城区已有地质资料整理分析的基础上,分析了深层地下空间开发的地质环境条件,开展了工程地质条件分区,评价了开发利用中所面临的重大地质问题,最后分别针对深基坑工程和隧道工程进行了工程建设适宜性评价。结果表明,上海深层地下空间开发中的工程地质条件较为复杂,深基坑工程和深部隧道工程建设适宜性为基本适宜至适宜性差。该成果为深层地下空间开发规划和建设提供了科学依据。

In Shanghai downtown area, most of the shallow and middle underground spaces have been used, and the development and utilization of underground space will develop and extend to the deep level. Based on analyzing the existing geological results, this paper evaluates the geo- environmental conditions during deep underground space development, and makes out divisions of the engineering geological condition. Also this paper assesses the major geological problems faced by deep underground space utilization. And finally, this paper assesses the feasibility of deep excavation project and tunnel project. The results indicate that engineering geological conditions are complicated for the deep underground space development, and the feasibility of deep excavation and tunnel project is arranged from basic suitability to bad suitability. These results can provide scientific basis for deep underground space plan and building.
