Abstract:

Rongjiang super-large bridge is a part of the highway from Chaozhou to Huizhou in Guangdong province which is near to Chaoshan civil airport crossing Rongjiang River. In order to ensure the normal navigation under the bridge and meet the requirements of Airfield Height Control, both the span and the height of the bridge are limited, thus the main span should not be less than 380m while the bridge heights of the pier on the Chaozhou and the other side should respectively not be more than 96.65m and 109m .Due to the double restrictions of span and bridge height, three schemes are considered which include the scheme of steel-concrete composite box girder low-pylon

cable-stayed bridge, self-anchored suspension bridge and prestressed steel truss-concrete composite through continuous rigid frame bridge which is proposed in this paper. Aiming at the prestressed steel truss-concrete composite through continuous rigid frame bridge, the design ideas are described, the general layout and the detailed construction are discussed and the mechanics property analysis

in period of construction and service are also made to demonstrate the feasibility and reasonability of this scheme under given conditions .
