摘要
厦门北站的站房采用上进下出,地铁线路按零距离换乘理念进行设计。为保证高铁的通车运营,整个工程采用站房先行施工,在站房正常使用后,线下地铁后续开挖的施工组织设计。高铁的正常运营对后续地铁的开挖变形提出了极为严格的要求。本文主要介绍了在厦门北站高铁既有线运营的条件下,明挖法线下地铁施工如何穿越大跨度连续刚架桥的基坑支护技术。
Xiamen North Railway Station is designed by using the progress under the subway line-concept of zero distance transfer. In order to ensure the operation of high-speed rail station, the station construction is fristly conducted,the subway excavation is followed up. The normal operation of high-speed rail subway excavation on subsequent deformation makes strict demands. In this paper, the retaining structure technology to control the deformation in the subway foundation pit excavation and subsequent process of Xiamen North Railway Station are mainly introduced.
