分离岛式暗挖车站的洞桩法结构设计

介绍了北京地铁十号线呼家楼站采用分离岛式洞桩法施工的结构设计，对该工法的结构原理、形式选取、施工步序及模拟计算进行了论述，说明邻近建筑物施工时，采用洞桩法设计可有效减小施工变形，对以后类似工程有一定的借鉴作用。

Structure design on metro station mining by the method of pile-beam-arc

The paper introduces the construction design method using the PBA in the Hujialou station using separated island form,one of the station of the 10th line of Beijing metro. It discusses the design logos of the station, makes technical discussions on the structure form extraction, structure form schemes and simulation computations. It proved that the PBA structure form and construction method can define the settlements and protect the buildings around the station effectively. It is hoped that the paper can provide some reference for the metro station designed in the simuliar case.
