地铁车站暗挖工程（PBA 工法）施工技术控制要点

摘要

结合具体工程实例，介绍了PBA工法施工工艺流程和控制要点，着重阐述了其施工准备阶段控制要点、施工过程中挖孔桩施工、土方开挖、临时支撑拆除等关键工序控制要点，为今后类似地下车站工程施工提供参考和借鉴。%Combining with specific engineering examples,the paper introduces construction technology procedures and control points of PBA method,mainly describes control points at construction preparation phase,excavation pile construction,earthwork excavation and temporary sup-port dismantle in construction process and other critical construction technology control points,which has provided some guidance for similar sub-way station engineering construction in future.
