This study investigates a turbulent wind-induced dynamic behavior of a soundproof tunnel structure with un-symmetric shape. The combined computational fluid dynamics (CFD) and fluid-structure interaction (FSI) simulations proposed in this study may allow us not only to investigate realistic wind effects but also to provide various parameters for the structural design. The CFD and FSI simulation were verified in comparisons with a full-scale experiment of soundproof frames. Subsequent simulation results present that displacements, stresses, and shear forces induced from the FSI analysis are heavily dependent on curved shapes and the wind direction of the soundproof tunnel. From parametric results, the technique proposed in this study is computationally efficient in characterizing behaviors for complex structures such as soundproof tunnels with un-symmetric shapes.

本研究调查了具有非对称形状的隔音隧道结构的湍流风致动力学行为。本研究中提出的计算流体动力学 (CFD) 和流固耦合 (FSI) 组合模拟不仅可以让我们研究真实的风效应，还可以为结构设计提供各种参数。CFD 和 FSI 模拟与隔音框架的全尺寸实验进行了比较。随后的模拟结果表明，由 FSI 分析引起的位移、应力和剪切力在很大程度上取决于隔音隧道的弯曲形状和风向。从参数结果来看，
