Shanxi-Henan-Shandong Railway thoroughfare,a railway with large coal transportation capacity,is for the first time designed with the heavy load standard in China. The main span of Fenhe River Bridge is a ( 46. 1 +2 ×76+46. 1) m continuous rigid frame prestressed concrete bridge. Its height is 47 m. This structure has higher bearing capacity and better seismic performance. In this paper,the structural design of the main span was introduced. T wo load standards,including ZH ( heavy load) and CR live load,were applied and compared. Seismic resistance was calculated and checked. Finally,the fixed joint between pier and girder was analyzed with a finite element solid model.
