摘要

基于三维数值模拟方法，模型考虑实地的地形地貌及毗邻建筑结构的影响，结合位置、风向、来流速度、线路等参数的变化，对百里风区吾普尔大桥挡风屏的遮蔽效应特性进行分析。研究表明：受到毗邻建筑的影响，挡风屏东西两侧的遮蔽效果较中段较弱；地貌结构使得挡风屏附近的涡旋结构增强。受到东侧挡风墙背风侧涡旋结构影响，使得下行线东侧的遮蔽效果明显优于上行线的遮蔽效果，速度折减系数差值约27%，而中段和西侧两线的遮蔽效果相差不大；来流速度的变化不会对挡风屏的遮蔽效果造成影响；风向角增大可以提高挡风屏的遮蔽效果。分析结果为挡风屏的抗风设计及列车的安全运行提供真实可信的参考依据。

Abstract

Based on three-dimensional numerical simulation method

considering the landform and the influence of the adjacent building structure

combined with the position

the direction of the wind

the change of the parameters such as flow velocity

lines

the Wu-Puer bridge windshield shading effect characteristics were analyzed. The study shows that

under the influence of adjacent buildings

windshield shading effect in the middle is weaker than that on either side of the windshield; landform structure makes the vortex structure stronger near the windshield. The vortex structure of the east wind-break wall leads to the shading effect of the east side of the lower line much better than the shading effect of the upper line

with the speed reduction factor difference of about 27%

while the defferences between the middle and west sides is small. The change of flow velocity does not affect the screen shield effect. The increased wind angle increases the shielding effect of the windshield. The analysis results provide a reliable reference for the windshield anti-wind design and the safety operation of the train.
