针对本文作者提出的大跨度梁式渡槽改进拟三维流固耦合模型,分析了该模型的三维模拟效果。分析结果显示,采用大跨度梁式渡槽的改进拟三维流固耦合模型不仅能很好地反映出三维耦合效应,而且可以有效降低计算成本,大大提高了计算效率。因此,改进拟三维流固耦合模型可以用于大型梁式渡槽多跨联合的复杂三维动力流固耦合分析计算。
For the improved pseudo 3D FSI model of large span beam aqueduct put forward by the first author of this article,research on the 3D seismic simulation effects of the model. Results showe that the simplifed FSI model reflects not only the good 3D seismic fsi effects, but also can significantly reduce the computing costs, greatly improving the computational efficiency. Therefore, the pesudo 3D FSI model can be used as a practical calculation method for multi-span joint 3D FSI seismic analysis of large-scale aqueduct.
