Paper Title:
Analysis and Computation Method of Prestressed Concrete Bridge in Construction Control
  Abstract

Based on solving the problems of pre-camber of the prestressed concrete bridge in construction, the calculation principle of the bridge model constructed in each stage is studied, the relation between forward and backward analysis method is illustrated, and the influencing factors related to characteristics of pre-camber and each controlled point are analyzed. Considering the influencing factors such as the establishment of new elements, the stressing of reinforcement, the shrinkage and creep of concrete in construction, the calculation model is established in accordance with the characteristics of prestressed concrete bridge constructed in each stage. The deformation of each construction segment is calculated with the forward and backward analysis method respectively, so that the pre-camber of each cantilever construction segment is gotten,which is the basis of construction control.
