[摘要]以北京地铁7号线东延工程万盛南街西口站—云景东路站区间1号联络通道为工程依托,针对国内地铁建设中盾构法区间联络通道施工时,因破除管片、地下水等导致联络通道施工风险大的问题,对1号联络通道采用冻结法的施工方案进行了研究。通过数值模拟及经典结构力学法分别进行设计计算,最终确定合理的冻结法设计方案及相应的设计参数。

Abstract:Taking the connecting passage between Wansheng South Street West Exit Station and Yunjing East Road Station of Beijing Metro Line 7 as the engineering support background.  Aiming at the problem of high risk in the construction of the connecting passage due to the removal of segments and groundwater during the construction of the shield tunnel connecting passage in the domestic subway construction, the construction plan of the No.1 connecting passage of this project using the freezing method is studied. Through numerical simulation and classical structural mechanics method respectively, the design calculation is carried out, and finally a reasonable freezing method design scheme and corresponding design parameters are determined.

Keywords:water rich sand; connected channel; freezing; design calculation; simulation
