地铁车站PBA工法施工技术研究

摘要

Combining with the engineering example,according to the underground excavation metro station,this paper mainly elaborated the comparison of underground excavation engineering methods,the characteristics,construction process and ground subsidence control measures of the PBA engineering method,provided a useful guide for choosing rational construction methods while building metro station of our country each big city.%结合工程实例,针对暗挖地铁车站,主要阐述了暗挖工法的比选、PBA工法的特点、施工工序及地层沉降控制措施,为我国各大城市修建地铁车站时选择合理的施工方法提供了有益的指导。
