| 摘 要： | 随着城市地铁建设的发展,盖挖法施工由于其独特的优势开始在车站施工选型中占据重要位置,它相对于明挖法来说影响交通和周边环境时间较短,对于缓解城市地面交通有着极大的帮助.而相对于暗挖法,盖挖法是在结构顶板或临时路面系统下进行暗挖作业,施工风险小.本文选取青岛地铁一期工程M3号线五四广场站的盖挖逆筑车站为研究对象,研究其围护...

| Abstract: | Covered excavation,as a construction method,greatly helps improvement of ground traffic conditions in the city.In this paper,the Wusiguangchang Square Station constructed by top-down method with covered excavation,a metro station on M3 Line of Stage I of Qingdao Metro,was selected to study influences of the settlements of surrounding piles(wall) and column piles as well as the differential settlements under top-down construction conditions on the internal stress in the structures.The analytical results can serve as guidance in directing both optimal design and practical construction. |
