| 摘 要： | 岩溶区域对地铁车站明挖基坑、结构施工以及建成后运营维护都有较大影响,为此,文章对岩溶区塌陷机理进行分析,研究提出提前对地铁车站岩溶地段进行处理,对溶洞、溶沟、溶槽填充,以及对溶洞间及溶洞与上层覆土间的水利联系进行阻断等技术措施,避免岩溶塌陷事故发生,以期为同类工程设计及施工提供借鉴。

| Abstract: | Karst area has a great impact on the open excavation of foundation pit,structural construction and operation and maintenance of metro station.Therefore,this paper analyzes the collapse mechanism of the karst area,studies and puts forward some technical measures such as dealing with the karst area of metro station in advance,filling the karst cave,karst ditch and karst tank,and blocking the water conservancy connection between the karst cave and the overlying soil,avoiding karst collapse accidents.It is expected to provide references for similar engineering design and construction. |
