摘要
北京地铁天安门西站历时7年(1992～1999)建成,其间对车站主体进行了多次方案研讨,经技术经济综合比较,把车站主体结构施工方法由“CRD”工法改为浅埋暗挖“洞、桩、墙”逆做法,文章对地铁车站初次采用“洞、桩、墙”法施工的细部方案设计作了较为系统的阐述。
It took seven years to finish the Tian'anmen West Station of Beijing Metro from 1992 to 1999 during which the scheme for the station 's main structure has been studied and discussed for many times, and finally the construction method was changed from 'CRD' to shallow depth & bored 'bottom up' method consisting of 'tunneling, piling & side wall 'after technical and economical comparison. The paper gives a systematic description of the detailed scheme design of this method that was firstly adopted in the metro station.
