地下结构逆作施工时水平与竖向结构节点处理方法

Handling Methods of Horizontal and Vertical Structure Nodes in Underground Structure Top-Down Construction

地下结构采用逆作法施工时,与常规的施工方法不同的是先施工水平结构,再施工竖向结构,水平与竖向结构节点施工质量对整个逆作法施工起到关键的作用。针对太原红星美凯龙项目地下结构采用局部逆作法施工,总结了逆作法结构相关节点施工工艺。可为北方地区类似工程提供参考。

There is a difference between top-down construction and traditional construction on underground structures, in construction sequence the vertical structure construction is after horizontal. The horizontal and vertical structure nodes play key role in top-down construction. This paper summarizes the construction technology of structure nodes in top-down construction according the top-down construction apply on underground structure of Macalline engineering in Taiyuan city. It can provide a reference to related engineering in north area.
