The two-span pre-stressed concrete variable height T-rigid frame box girder is adopted for the bridge across Guangzhou-Shenzhen Railway in Shenzhen Outer-Ring Expressway. The span is 2 × 82.5 m and the deck width is 33 m. The plane swivel method is used in the construction. The swivel angle is 72.342°. The cantilever length of the swivel structure is 2×73.5 m, and the swivel weight is 24 000 tons, which refreshes the width and weight records of swivel bridges within the jurisdiction of China Railway Guangzhou Bureau Group. In the trial swiveling stage of this bridge, the technical parameters are provided for the formal swivel through weighing test, trial swiveling test and inch-moving test, which ensure the smooth swivelling. The completion of the bridge ensures the smooth opening of Shenzhen Outer-Ring Expressway according to the plan, and accumulates the valuable experience for the design and construction of large tonnage swivel bridges in China.
