earth-anchored suspension bridge; steel stiffening truss girder; double-decked bridge; gravity anchorage

The main bridge of Dalian South Binhai Avenue is a double-decked three-span earth -anchored suspension bridge with a full length of 820m, of which the main span is 460m, and a width of 24.8m. In this paper, the conceptual design of the steel stiffening truss girder, cable tower and anchorage are introduced and the design difficulties and points are analyzed. The anchorage adopts the hollow triangular frame structure, breaking through the physical heavy structure of gravity anchorage; and the design of two wedge-shaped gravel bed foundations improves the anti-slip safety factor of the anchorage. The offshore anchorage program provides a reference for the construction of future similar bridges.
