Bridges monitor and control plays a important part in the bridge construction technology. Besides, It is the key factors of ensuring the bridge construction safety in the construction project and meeting design and construction code requirements. The Article takes a high-speed railway bridge as engineering background, and adaptive control system will be applied to the monitoring measurement. The Main Parameter of construction is proposed, which is based on the sensitivity analysis of design parameter in theory. According to take elastic modulus and volume weight of concrete as the main Parameters, identified and adjusted them by least square method, to forecast errors, analyze and adjust parameters. Using the adaptive control system to collect the data of displacement and stress in bridge construction.Calculate through the Computer simulation model, and obtain initialize height during construction, on this basis, guiding the construction and complete the construction of control successfully.
