Analysis of Long-Term Deflection on Large-Span Continuous Rigid Bridge

Article Preview

Abstract:

Through the long-term deflection observation results and the measured data of effective pre-stress of Humen bridge before and after reinforcement, using three-phase bridge long-term deflection calculation method, compare the measured data and the calculation conditions in three kinds. Basing on the measure value of construction degradation, presenting the long-term deflection correction coefficient of long-term deflection to predict construction deflection. Analysis results show that the calculation model considering the construction degradation is more close to the practical situation. The long-term deflection calculation method based on the coefficient of correction can be used in the prediction calculation.
