Abstract
The main bridge of Dongping grand railway bridge is a ( 85+286+85 ) m-span with double arch rib connected by steel truss arch bridge. The upper arch rib of the main bridge extends to the side pier bearings and the lower arch rib is supported on the middle piers. The upper and the lower arch ribs are connected by truss structures. The side spans of the main bridge are arch structures, which support bridge deck system with arch columns. The ratio of side span to middle span is only 0. 3. The bridge deck system is an orthotropic plate structure with horizontal K-shape supports. The bridge structure and the bridge deck system are the first application in China, which add more choices to railway bridge structure and design. The structure is well designed, simple and clear in force bearing.关键词
