Abstract

At present, the underwater bridge foundation construction technology in China and abroad has been relatively mature, but the different geographical environments, hydrogeological conditions, the form of basic structure, and the available construction equipment lead to different construction schemes and technologies. The Beitstadsund Bridge in Norway is located near the Arctic Circle in central Norway and across the strait. In the design and construction of the deep-water steel cofferdam of the inclined steel pile cap for the bridge, the overall installation of the steel cofferdam was realized by setting the cofferdam support on the inclined steel pipe group, the overall positioning and installation of the cofferdam, the steel-concrete composite plate bottom sealing, and the vertical anti-floating rock anchor. The application results of the bridge show that the steel cofferdam design and the overall installation process have better safety and practicability.
