Analysis of Forces Acting on Steel Cofferdam for Deep-water Foundation

The steel cofferdam has been widely employed in the construction of the main piers and foundation project of grand bridges for its advantages contrasted with other construction methods. Since the dimensions and loads imposed on the single-wall steel cofferdam of deep-water foundation for Yuxi Road Bridge in Chaohu city are large and the structure is complex, three-dimensional analysis by means of FEM program for force status of the monolithic structure has been made in order to study its mechanic features and ensure its construction safety. The analysis results show that strength and stability of the single-wall steel cofferdam satisfies engineering requirements. The conclusions may serve as guidance and reference for the design and construction of similar structures.
