长联大跨径的刚构连续组合梁桥采用“弯梁”形式布置 (曲线梁 ) ,不但具有刚构连续组合梁桥的优点 ,而且充分体现曲线梁在桥梁设计和选线上的灵活性 ,能更好地适应道路线型。以党家沟大桥为实例 ,介绍长联大跨径刚构连续组合弯梁的线形控制、0 #段悬臂托架施工、1#段无托架施工、2 #～ 13#段悬臂挂篮施工以及合龙与体系转换等关键施工技术。
The long-span long-span continuous composite beam bridge with “curved beam” layout (curved beam) not only has the advantages of rigid frame continuous composite beam bridge, but also fully reflects the flexibility of curved beam in bridge design and alignment , Can better adapt to the road line. Take the case of Danggougou Bridge as an example, this paper introduces the linear control of Longgang large-span rigid frame continuous composite curved beam, construction of 0 # section cantilever bracket, 1 # without bracket construction, 2 # ~ 13 # cantilever hanging basket construction As well as the key construction technology such as closing and system conversion.
