Abstract:

Hetonghuang Bridge is a box- cross-section basket arch bridge spanning 280m. Within the scope of the main bridge project, the plane linear circular curve is connected to the straight line, which is located on the 2.074% one-way longitudinal slope. The steel box section is adopted for the arch rib. The width of the main bridge deck structure is 31.0 m, and the outside of the bridge is on the left and right. Based on this project, the key technology of manufacture and installation of box cross section basket arch bridge is discussed.
