摘要
荆岳长江公路大桥主桥为主跨816m双塔不对称混合梁斜拉桥,主梁钢混结合段采用带钢格室的部分连接填充混凝土形式。该文主要是对钢混结合段连接形式进行分析比选,对结合段细部构造如承压板、剪力键、钢格室、预应力筋等合理构造进行分析研究,最后通过受力计算分析,验证预制拼装式混合梁的安全性。
The main bridge of JingYue Yangtze river bridge is a asymmetric hybrid girder cable-stayed bridge with a main span 816 m.The steel-concrete composite segment of the girder is composed of the steel box room packing concrete structure with part connected.In this paper,joint form of the steel-concrete composite segment is analysed and compared.It was analyzed and researched the proper detailed structure of steel-concrete composite segment(for example,the bearing plate,the shear connector,shear connector and prestress distribution).Finally,through the force calculation and analysis,verify the safety of the precast hybrid girder.
