摘要
介绍了主跨220m预应力混凝土刚构—连续组合梁桥超长钻孔桩基础、双薄壁墩间距及壁厚、箱梁合龙顺序及主跨合龙前跨中预施水平顶力等设计研究结果,对在第四系海陆交互相沉积层地质条件下设计大跨径预应力混凝土连续结构梁桥具有参考价值。
This paper presents the findings of design case study of the particularly deep bored pile foundations, spacing and wall thickness of the doublethinwalled piers, closure sequence of box girder, and preapplied horizontal jacking force at midspan prior to the closure of main span of a prestressed concrete hybrid bridge of rigid framecontinuous girders with main span length 200 m, which offers reference to the design of longspan prestressed concrete continuous bridges under geological conditions of quaternary sediment of sealand crisscross facies.
