管线保护对地铁车站设计的影响——以桩间挡板和盾构平移为例

Influence of Pipeline Protection on Subway Station Design:Case Studies of Baffle of Soldier Pile Wall and Shield Translation

通过设置桩间挡板和站内盾构平移满足电力管线保护需求,基于桩间挡板和两侧桩体共同承担缺失桩体范围内的主动土压力,完成地铁基坑桩间挡板设计,提出车站盾构平移始发的结构设计要点,为类似工程设计提供参考。

The power pipeline protection needs are met by setting up baffles of soldier pile wall and in-station shield translation, and the design of the baffles in subway foundation pits is completed based on the active earth pressure within the missing piles of the baffles and the sides of the piles. The key points of structural design of shield translation in station are proposed to provide reference for similar engineering design.
