Design of Railway Bridges at Basement Waiting Rooms of Qingdao Passenger Station

青岛客站地下候车室铁路桥由5座独立、平行的双线铁路桥组成,采用简支箱式槽形梁结构,每座桥均由梁长39.65 m的预应力钢筋混凝土梁和梁长13.00 m的普通钢筋混凝土梁各1孔组成。介绍全桥中具代表性的2号桥的上部结构和下部结构设计。

The railway bridges at the basement waiting rooms of Qingdao Passenger Station include totally five independent and parallel double-track bridges that were designed as the simply-supported box channel girder structures with each of the bridges composed of a span of prestressed concrete girder 39.65 m in length and a span of reinforced concrete girder 13.00 m in length. In this paper, the design of both the substructure and superstructure of the typical Bridge No. 2 among the five is presented.
