| Abstract: | The upper structure of the 3rd contract section of the viaduct in Jihan East 2nd ring road is simple support gird- er plus continuous box girder, and the lower structure is portal pier. The pier is 18.1 ~26.5 m high, and a large volume cap beam was put on top of the pier, which is 3 m high, 2.6 m wide, with a clear span of 24.7 m. The paper gives a brief introduction of the construction of the cap beam with steel tubular truss method. |
