陶赖昭松花江特大桥悬臂浇筑阶段高程控制

Height control in cantilever construction of Taolaizhao Songhuajiang River Large Bridge

陶赖昭大桥的施工采用悬臂浇筑法施工。施工高程控制 ,即悬臂段标高控制是保证施工质量以及桥梁结构体系顺利合拢的关键。本文综合考虑影响施工高程控制的相关因素 ,确立了悬臂浇筑各阶段的立模标高 ,并对结果进行了修正。

Taolaizhao SongHua River Large Bridge are built by using cantilever_construction. The height control is the key points to the construction quality and to ensure the success of bridge closure. The paper expounds the factors concerned on the height control, makes the correct height points of separate cantilever segments. The results are amended according to the relevant factors.
