本文针对大跨度斜拉桥等大型复杂桥梁结构大多采用节段施工的特点,将子结构技术与节段施工方法结合起来进行桥梁施工全过程仿真分析。在阐述子结构技术分析方法的基础上,寻求合理的子结构划分方法来模拟斜拉桥的施工进程,并应用有限元分析软件ANSYS的子结构分析功能,对一座独塔斜拉桥实现了施工全过程仿真分析。结果表明,利用子结构技术可以简化施工过程的模拟并大大缩短计算时间,特别适用于复杂模型的桥梁结构分析。
In this paper, large-span cable-stayed bridges and other large-scale complex bridge structures mostly adopt the characteristics of segment construction. The sub-structure technology and segment construction methods are combined to simulate the whole process of bridge construction. On the basis of expatiating on the substructure technical analysis method, this paper tries to find a reasonable sub-structure division method to simulate the construction process of the cable-stayed bridge and applies the substructure analysis function of the finite element analysis software ANSYS to realize the construction of a single pylon cable-stayed bridge The whole process of simulation analysis. The results show that the use of substructure technology can simplify the construction process simulation and greatly shorten the calculation time, especially for the bridge structure analysis of complex models.
