| Abstract: | 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 example, 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. |
