Aerodynamic Optimization of the Windscreens for Railway Bridge in Strong Wind Areas

Abstract:

With the development of economy and technology, many high-speed railways have been constructed. However, many of these railway lines have to pass through strong wind areas, and the cross wind in these areas would reduce the operational safety, thus windscreen is an effective facility in many engineering cases to protect the running trains from strong winds. There are two kinds of windscreen, the unilateral windscreen and the enclosed windscreen. By numerical wind tunnel technique, the impacts of the two kinds of windscreen on the lateral force acted on the running trains are analyzed, meanwhile the operational safety could be also evaluated. According to the research results, the moment coefficient has a relatively small variation when the height of the windscreen is more than 3m. The unilateral windscreen with a ventilation rate of 20% is more favorable for the operational safety than the enclosed windscreen.
