A Study on the Effects of the Train Gust induced by High speed train at 350km/h on the Simple Vertical Surfaces Parallel to the Track

고속열차 350km/h 주행시 열차풍이 방음벽 등 궤도에 수직평행한 선로변 구축물에 미치는 영향에 관한 연구

After rapid running is begun in domestic, problem by the train gust that was not considered at existent train running appeared. If the High-Speed railway business speed rises by 350km/h in the future, is going to become more big problem. This study conducts an experiment that measure in local about KTX train beside Gyeong-Bu High speed railroad track about aerodynamics effect that happen by passage of train and analyzed. In case KTX II runs with the 350km/h speed, forecasted effect that get in the simple vertical surfaces parallel to tracks according to distance from rail center. Compared construction size with structural analysis in case do not consider with case that consider the train gust about sound proof walls representatively. As a result, proposed wind load standard that apply at sound proof walls design.
