摘要
通过对北京地铁四号线圆明园车站盾构过站施工的总结及分析,着重从调整盾构掘进轴线、变更围护结构形式、车站端头加固等几方面介绍盾构在车站未施工前直接过站对车站的后期施工造成的施工难点及为保证车站施工所采取的相应技术措施。
Based on the analysis of the shield machine's crossing Yuanmingyuan station on metro line No.4 in Beijing, this paper discusses mainly the adjustment of the shield axis, the change of support structure and the reinforcement of the ends of station. And, the technical difficulties in the construction of subway station are researched because the shield machine crosses the station before the station begins to construct. At last, the technical measures are presented in this paper.
