Main bridge special-shaped inverse trangle structure construction technology of Yingzhou large bridge in Luoyang

针对洛阳瀛洲大桥主桥异型倒三角结构受力复杂,两斜肢为不对称结构,施工难度很大的问题,从施工方案的确定、支架的设计施工、模板和混凝土施工及施工监控监测等方面论述,解决了异型倒三角结构的施工技术难题。

Aiming at the problem that the main bridge special-shaped inverse trangle structure on Yingzhou large bridge in Luoyang,its stress is complex,two inclined limbs are asymmetric structure,and its construction is very difficult,the author discusses the construction scheme confirming,design construction of the supporting,template and concrete construction,and construction supervision,and solves the construction technology problems of the special-shaped inverse trangle.
