摘要
以珠海市高栏港高速公路新城市大道跨线桥25m装配式连续小箱梁桥的大悬臂T型墩预应力盖梁设计为实例,介绍此类盖梁的设计过程及计算模型,重点阐述盖梁活载选取不同的横向加载方式时对计算结果的影响,从而制定出适合此类盖梁设计的计算方法,可为类似工程提供参考。
Taking the design of large cantilever T-type pier prestressed capping beam of 25m fabricated continuous small box girder bridge of New City Avenue Overpass at Zhuhai Gaolan Port Expressway as an exam- ple, it introduces the design process and the calculation model of the beam; and focuses on the influence on the calculation results by different transverse loading type of capping beam live load, in order to make calculation method suitable for the design of such beam. It can provide reference for the similar projects.
