| Abstract: | Shibao Bridge is a cast-in-situ reinforced concrete box zero thrust three-arch bridge （56.00 m ＋ 83.50 m ＋ 56.00 m） in Chongqing, with adopting the construction method of cradle cantilever symmetric casting. The balanced thrust feature of zero thrust arch bridge is introduced in the paper. Meanwhile, the pier foundation, basic structure and superstructure are presented from the angle of structural design. Finally, the construction steps and key points of the superstructure are put forward. |
