摘要
以一座在建200 m连续刚构桥为工程背景,利用有限元方法建立仿真分析模型,模拟桥梁施工及成桥状态,分析各施工阶段桥梁结构的变形及应力,并与现场实测数据进行对比分析,为大桥施工控制提供参考。
Taking a 200m continuous steel structure bridge under construction as the project background, this paper establishes a simulation analysis model by means of the Finite Element Method to simulate construction and completion states, to analyze deformation and stress of structure during various construction phases, and to compare with the measured data on site in order to provide a reference for construction control of bridges.
