The construction control is very important to the construction quality of long-pan continuous beam bridge, so a self-adaptive construction control analysis method is proposed. A construction self-adaptive control system is established in this paper, which is based on the self-adaptive control theory and the characteristic of long-pan continuous beam bridge construction. The sensitivity analysis method is used to choose the most important parameters. The least squares method is utilized to parameter identification. The construction forecast control is also included in the construction self-adaptive control system. The analysis result of a beam bridge shows that the self-adaptive construction control analysis method is feasible and reasonable.
