| Abstract: | The movable bridge at Haihe river is taken as an example in this paper. A 3 D numerical analysis model, taking into account the complete process of construction, is established to study the mechanical characteristics of the movable bridge with steel box girders. he stress level and distribution characteristic of the movable bridge is analyzed, which provides technology reference for the construction of Haihe river movable bridge with steel box girders.The finite element analysis method of this bridge is suitable for similar bridge construction. |
