摘要
鄂黄长江公路大桥为双塔双索面预应力混凝土斜拉桥,主跨跨径480m,施工难度大且主要集中在主梁。着重介绍预应力混凝土双肋板式主梁施工的主要技术,包括前支点挂篮悬浇、后支点挂篮悬浇、施工监控、临时墩、施工控制要点等。
Ezhou\|Huanggang Changjiang River Highway Bridge, with a main span 480 m, is a prestressed concrete (PC) cable\|stayed bridge of twin pylons and twin cable planes. The construction of the Bridge is of peculiar difficulties, particularly that of the main girder. In this paper, the principal construction techniques for PC double\|rib plate girder, such as casting of concrete with cantilever method with fore\| and rear\|support traveling carriages, construction monitoring, temporary piers and construction control, are mainly dealt with.
