| 摘 要： | 以一座实桥为工程背景,对采用分节段悬臂浇筑施工的大跨度桥梁结构施工控制过程中的变形控制进行了研究,提出了变形控制过程和实现的方法．同时根据所采用国际通用大型计算软件一ANSYS软件,应用“生”、“死”单元的方法,建立了统一计算模型,即：全桥模型,减小了计算工作量．最后,通过对该实桥变形监控结果的分析,证明了本文所提方法的正确性和有效性．

| Abstract: | In this paper, the deformation control in the construction control of long-span bridges using the segmental cantilever method is studied, with regards to some engineering examples. In order to reduce calculation work, the "live" and "dead" elements are used and the general computing model is established. In view of the actual deformation measurement of the correctness and effectiveness of the control method for one bridge proposed in this paper is proved. |
