2010年1月 施工技术 第39卷第1期 CONSTRUCTION TECHNOLOGY 天津站交通枢纽逆作法立柱竖向位移监测与分析 王文灿,仲晓梅,詹学智2 (1.天津城市建设学院土木工程系,天津300384:2.中铁一局天津公司,天津300250) 【摘要]天津站交通枢纽工程采用盖挖逆作法施工。深基坑开挖过程中坑底回弹会带动立柱上浮,立柱的竖向位 移可以引起水平支撑结构和围护结构之间的附加弯矩,而立柱之间的差异竖向位移过大会对作为水久结构的水平 梁板结构产生不利影响。因此控制立柱的竖向位移及差异竖向位移是超深基坑工程设计和施工中需重点考虑的 问题。通过系统监测超深条形基坑开挖过程中不同断面处立柱的竖向位移,考虑影响基坑立柱竖向位移的相关因 素,分析得立柱桩的竖向位移随时间和空间变化的规律。 【关键词超深基坑逆作法;支撑立柱;竖向位移;时空效应 【中图分类号】TU443 【文献标识码]A 文章编号1002-8498(2010)01-0067-04 Analysis and Monitoring on Supporting Column Vertical Displacement in Tianjin Railway Station Traffic Hub with Top-down Construction Method Wang Wencan' ,Zhong Xiaomei' ,Zhan Xuezhi ( 1.Civil Engineering Department ,Tianjin Institute of Urban Construction ,Tianjin 300384 ,China ; 2 .Tianjin Branch of China Railway First Group Co .,.Tianjin 300250 ,China ) Abstract :Tianjin Railway Station traffic hub is constructed with cover excavation and top-down construction method .The bottom rebound of foundation excavation will hoist the support column ,and the vertical displacement support columns could bring plementary moment between horizontal supporting structure and wall .Furthermore ,the differential vertical displacement between support columns will h...
