摘要
随着城市轨道交通的快速发展,城市中心区域的地铁车站深基坑工程越来越多,但这些地下车站施工建设均面临着周边建筑物密集、地下管线众多、环境保护要求高、交通压力大、施工场地狭小的困境。结合工程实例,介绍了轨道交通地下车站深基坑的逆作法施工技术,为有效解决城市轨道交通地下车站的施工难题提供参考。
With rapid development of urban rail transit, more and more deep foundation pit projects of subway station in downtown area have been put into construction. However, the construction of these underground stations have confronted with some difficulties like dense surrounding buildings, numerous underground pipelines, high requirement of environmental protection, high traffic pressure, and narrow construction site. Combined with engineering example, the reversed construction technology for deep foundation pit in rail transit underground station has been introduced, which can provide references for effective solution to construction difficulties of urban rail transit underground station.
