摘要
北京地铁十号线呼家楼站位于东三环路面下,紧邻京广立交桥,周边环境复杂。经比选,车站采用分离式结构设计,洞桩法施工,增加了工程的安全性和稳定性。介绍了呼家楼站的结构设计和计算,对其结构形式的选取、施工步序及模拟计算进行了论述。实践证明,采用洞桩法设计可减小施工过程中产生的变形,有效保护临近建(构)筑物。
Being located under East 3rd Circle Road and adjacent to Jingguang Flyover, Hujialou station of Line 10 of Beijing Metro is situated under complex surrounding environment. After comparison and contrast, separated island structure and PBA （Pile-Beam-Arch） construction method are determined for the Metro station so as to improve the safety and stability of the works. The article presents the structural design and calculations of Hujialou station and expatiates on the structural type selection, construction steps and simulation computation of the Metro station. The practice shows that, by adopting the PBA method, the deformation occurring during construction can be reduced and the adjacent structures can be effectively protected.
