【摘要】 波折钢腹板组合箱梁桥是一种新型桥梁结构体系,通过利用波折形钢板来替代混凝土箱梁的腹板, 从而达到减轻结构自重、提高预应力施加效率的目的,同时又可解除箱梁腹板与顶底板的相互约束并减小温差、干燥收缩以及徐变的不利影响.以某公路桥设计为例,介绍了其主要技术参数取值以及波折钢腹板与混凝土顶底板、混凝土横隔板的连接等构造上采取的技术措施,并对结构计算和施工方案简要介绍,为该类桥梁的设计提供参考.更多还原

【Abstract】 The composite box girder bridge with corrugated steel webs is a new structure with corrugated steel webs instead of concrete webs.It can lighten the structure weight,develop the efficiency of the application to the prestressing force and relieve the effects of the constraints between the webs and the flanges and reduce the disadvantage effects of temperatures,drying shrinkage and creep.This paper introduces the design method of a highway bridge and the technical measures used in structures such as connections among the corrugated webs, the concrete flanges and the concrete diaphragm plates,which can provide the reference to the design of this kind of the bridge.更多还原
