The Wushan Bridge ( Chinese 巫山 长江 大桥 ) is a road bridge in the area of the government- direct city of Chongqing in the People's Republic of China , which leads the provincial road S 301 at the place Wushan over the Yangtze River .
location
After the Badong Bridge, it is the second bridge over the Yangtze River above the Three Gorges Dam, 120 kilometers away . The closest bridge up the river is Fengjie Bridge, 45 km away . It is 485 kilometers by river to the center of the actual city of Chongqing.
Wushan is only 3 km as the crow flies from the bridge, but the road has to make a 15 km detour over the mouth of the Daning River.
description
The total 612.2 m long Wushan Bridge crosses the Yangtze River with a single large arch with a span of 460 m. It is one of the ten largest arch bridges and is the second largest CFST bridge (tubular steel arch bridge filled with concrete) in the world after the Bosideng Bridge .
It has two lanes in each direction, which are only separated by a center line, and a 2 m wide walkway on both sides. It is 19 m wide.
From a technical point of view, it is a CFST bridge with a roadway suspended at about half the height. The two supporting arches each consist of four parallel steel tubes with a diameter of 122 cm and wall thicknesses of 22 mm to 25 mm in the sections above the transom . These pipes are connected and stiffened by narrower pipes. The two arches are also stiffened at regular intervals by cross bracing made of steel tubes.
In the construction were above the two fighters at a distance of 576 m 150 m high two steel lattice towers erected and anchored back in the slopes through which a cable crane of up to 170 t heavy parts running, a maximum of 260 could lift m high. These towers also served to back anchoring of the cantilever mounted arches. When construction began, the level of the carriageway was still 180 m above the water level of the Yangtze.
After the bridge arches had been completed, their steel pipes were filled with concrete and the corrosion protection already applied in the factory was given the last layer. Finally, the carriageway slab was suspended in sections into the arch structure and raised on narrow steel supports at the sides.
The Wushan Bridge opened on January 8, 2005, when the Three Gorges Reservoir had not yet reached its destination .
When the reservoir is completely filled, the water level will reach just below the fighter so that the roadway is only 76.4 m above the storage target of 175 m above sea level. d. M. or 106 m above the lowering target .
