| Abstract: | A bridge over strait with main span of 270 m is a half-through steel pipe concrete arch bridge. To cast concrete at main arch rib is another key procedure after the closure of arch rib. In addition, the field construction is limited by a few of factors. The paper describes the construction plan, construction technology and quality monitoring of casting main arch rib. |
