摘要
北京地铁5号线磁器口车站主体结构大部分位于粉细砂、细砂及中粗砂层中,结构埋深10m左右,采用中洞法施工。由于地质条件多为砂层,施工环境复杂,对地表沉降要求严格,主要阐述车站主体的施工方法,对施工各阶段地表沉降原因进行分析,提出车站施工中的相关建议。
Ciqikou Station on Beijing Metro Line #5 is primarily located in super fine sand, fine sand, and medium and coarse sand stratum with a buried depth of 10m. Central excavation method was used. The complicated sand environment has high demand over ground surface settlement. A description is given of construction of the station, and analysis was made of causes for settlement during each construction stage, and countermeasures were given.
