| Abstract: |
The Lancang River railway arch bridge, a key project, is located on Dali~Ruili Railway with a design speed of 140 km/h. The bridge spans over the Lancang River, with the max slope angle of the mountain body on both sides of the river being more than 80 degrees. The distance between the bridge deck and the river surface exceeds 270 m. The whole bridge is 528.1 m long and the main span is 342 m. The x-style arch rib is a deck-type concrete-filled steel tube stiffened skeleton, which becomes the main arch structure of single-box single-cell box section after swing erection, by means of filling the inner space and covering the outer face with concrete. |
