地铁车站所处的建筑环境极其复杂，对于多层多跨的大型综合性地铁车站一般应首选盖挖逆作法施工。
As the building environment at metro station is complex, cover and cut method should be chosen at first for the large - scaled metro station.
在盖挖逆作法施工中采用“一桩两用”技术，不仅可节约大量费用，而且使地下结构的外墙的受力状态更为合理。
The application of dual-purpose pile in topdown construction can not only save costs, but also make the mechanic condition of substructure walls more rational.
