摘　　要：文中以湖南某项目上跨既有高速3座相同桥跨的现浇箱梁为例,对比了贝雷片和工字钢主梁的受力特征,对其进行了施工方案比选及结构验算,最终根据各桥特征确定了这两种现浇支架主梁的同时应用,并总结了其允许承载能力及挠度的相对关系,可为后续类似工程提供快速计算的方法及实施经验的参考。Taking the example of cast-in-place box girders of three identical spans across an existing highway in a project in Hunan Province,the paper compares the force characteristics of bailey beam and I-beams,compares the construction scheme and structural checking,finally determines the simultaneous application of these two kinds of cast-in-place support main girders according to the characteristics of each bridge,and summarizes the relative relationship between their permissible load carrying capacities and deflections,which can provide the method of rapid calculation and implementation experience reference for the subsequent similar projects.It can provide a quick calculation method and a reference of implementation experience for similar projects in the future.
