摘要
福厦客运专线中亚城特大桥为大跨度预应力混凝土连续梁桥,以其为工程背景建立有限元模型,分析悬臂施工中影响预拱度的各项因素,通过合理的计算方法和理论分析确定了桥梁施工过程中在受力和变形方面的工作状态,为类似桥梁工程的施工控制分析提供了参考。
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.
