摘要

横风对桥面或行车道上道路车辆的不利影响日益受到关注。当地的流动特性取决于桥梁的结构,风障通常用于缓解风引起的车辆不稳定性。地形地貌是另一个主要因素。本研究使用了一座沿海桥梁(台湾澎湖陈公桥)的地形模型。该桥位于水库和台湾海峡之间。由于秋冬季季风较强,曾发生过多次事故。在风洞试验中,建立了大气边界层,试验条件(风速和风入射角)取自当地气象数据。确定了固体风障的高度对当地风向和风速的影响。实验结果可用于改造防风屏障,以提高道路车辆的安全性。

The Effect of wind barriers on the local wind field on a bridge deck
The adverse effect of crosswinds on road vehicles on a bridge deck or traffic lanes is of increasing concern. Local flow characteristics depend on the bridge's architecture and wind barriers are commonly used to alleviate wind-induced instability for vehicles. Terrain orography is another dominant factor. This study uses a terrain model with a coastal bridge (Chen-Kung Bridge, Penghu, Taiwan). The bridge is located between a reservoir and the Taiwan Strait. Numerous accidents have occurred due to strong monsoon winds in autumn and winter. In wind tunnel experiments, an atmosphere boundary layer is established and the test conditions (wind speed and wind incidence) are taken from local meteorological data. The effect of the height of solid wind barriers on local wind direction and speed is determined. The results can be used to remodel wind barriers to increase safety for road vehicles.

期刊介绍: The objective of the Journal of Mechanics is to provide an international forum to foster exchange of ideas among mechanics communities in different parts of world. The Journal of Mechanics publishes original research in all fields of theoretical and applied mechanics. The Journal especially welcomes papers that are related to recent technological advances. The contributions, which may be analytical, experimental or numerical, should be of significance to the progress of mechanics. Papers which are merely illustrations of established principles and procedures will generally not be accepted. Reports that are of technical interest are published as short articles. Review articles are published only by invitation.
