Abstract: | Jiujiang Yangtze River Highway Bridge main span of 818m hybrid girder cable -stayed bridge is the largest monolithic concrete box girder sections hybrid girder cable -stayed bridge. The concrete box girder uses roof and floor with a small beam integral single box 3 -room structure. This paper describes the mass concrete design, construction techniques, some of the research results and experiences, and provides a reference for future similar projects. |
