Three walking paths of the pedestrian bridge of Meixi Lake Meiling Park across the Dragon King Kong River cross each other, steel structures twisted to three direetions, and the river is not allowed to pile up. Therefore, the overall construction of the steel bridge is very difficult. In this paper,the steel structure construction difficulties and countermeasures are analyzed, the key construction technology of steel structure is introduced and the numerical simulation analysis of the whole process of steel structure construction is carried on. The analysis shows that the structural deformation, stress and supporting reaelion of all the construction steps can meet the design requirements. Taking the method of diret＇t hoisting, the walking bridge construction task was completed successfully.
