| Abstract: | The steel box cofferdam has been widely employed in the construction of long bridges for its advantages contrasted with other construction methods. Construction technique and method of suspended steel box cofferdam are introduced in conjunction with the construction of Anqing Highway Bridge over Yangtze River. Since its dimensions and loads imposed on it are large and the structure is complex, nonlinear simulation analysis of the monolithic structure by means of FEM has been made in order to study its mechanic features and ensure its construction safety. The conclusions drawn from this paper may serve as guidance and reference for the design and construction of similar structures. |
