武汉城市地下空间工程地质研究

Engineering geological research on the underground space of Wuhan City

利用武汉市现有勘察资料,初步分析研究城市地下空间的物质载体及其空间组合关系,从空间岩土体工程地质性质和赋水条件入手,研究得出武汉城市地下空间的利用存在岩溶地面塌陷、地下水作用、软土变形三大工程地质问题。在此基础上进行地下空间利用区划,指出各区在地下工程建设中需要重点防范的工程地质问题和合理利用地下空间的方法。最后以武汉地铁首期工程为例,分析工程地质优势与问题,提出防范问题的措施建议。

By using the Wuhan existing reconnaissance material, the researchers preliminarily analysis and study on the material carrier of the city underground space and the spatial combination relations. Beginning with the spatial engineering geologic characteristics of rock mass and the water-beating conditions, three serious engineering geologic problems in the use of Wuhan City underground space are proposed, such as karst collapse, underground water function, soft soil deformation. Hence, the authors claim that the use of the underground spatial should be divided into districts, not only point out various engineering geologic problems that need to be on guard but also give some reasonable methods how to use underground space. Finally taking the first period project of Wuhan subway as example, the superiority and problem of engineering geology are analyzed and some effective measures and proposals are put forward. The research results will be helpful for the plan of Wuhan urban district underground engineering construction, the reconnaissance design and the construction organization.
