| Abstract: | Shijiahe Bridge of Baotou-Xi＇ an Railway is difficult to build which has high piers, bulk bent caps and long cantilevers in complicated terrains. Combined with the bent cap construction in this bridge, structural design, checking and prestress of section steel-Bailay beam composite brackets are introduced, which not only ensure the construction quality and safety of the bent caps, but also achieve good economic benefits as a reference to similar projects. |
