| Abstract: | Zhong Ya Cheng bridge in Fu-Xia Passenger Railway Special Line is a prestressed concrete long-span continous bridge.Based on it, this paper build a FEM model to analyze the infulence of construction procedure on the pre-camber setting of this bridges . By introduction of new calculating theroy and method, the mechanics and deformation characteristics of this bridge is revealed clearly, which can be referenced by others similar bridges. |
