| Abstract: | Xinyang bridge is a long-span prestressed concrete arch continuous beam bridge. This paper introduced design and key construction technologies of the bridge, and made finite element analysis on the V leg rigid frame. Then key technologies of the V type rigid frame construction were discussed, and corresponding countermeasures were put forward. |
