| Abstract: | Based on the inherent requirements of bridge structures, the primary characteristics of the prestressing technology are analyzed. The typical applications of prestressing technology in bridge structures are introduced, which include concrete continuous girder bridges, cable-stayed bridge, cable suspension bridge, pre-flex prestressing concrete girder bridge, transverse tension bridge. At last, the problems of application of prestressing technology in bridge structures are analyzed. With the development of prestressing technology, future prestressing bridges shall step towards larger span, greater load bearing, and greater durability. |
