| Abstract: | Concrete-filled steel tube rib solved two problems of the application of high-strength material in arch bridge and the construction with less supports, which has been rapidly developed in bridge. Through the example of large bridge across highway in Shanghai-Nanjing High-speed Railway, the construction technology,process and difficulties of concrete-filled steel tube rib for through-type tied arch bridge are discussed. It been proven from practice that the construction technology not only ensured engineering quality, but also shortened construction period. |
