The results show that: the velocity peak value of longitudinal train wind is 4.4 times and 2.6 times of transverse and vertical train wind at a typical position above tunnel rail line; when train head passing by the crossing region of high-speed railway tunnel, eddy current is formed at the typical position, and the speed of train wind is over 20 m/s in single tunnel; shaft will cause the train wind speed within the cross region of tunnel 45 m range greater than the general region of tunnel; when a train passing by the crossing region of single and double line tunnel, the velocity peak value of longitudinal train wind is 20.16 m/s and 18.20 m/s at the typical position above tunnel rail line %K 高速铁路 %K 隧道 %K 竖井 %K 列车风< %K br> %K < %K /B> %K high-speed railway %K tunnel %K shaft %K train wind %U http://www.jrse.cn/paper/paperView.aspx?id=paper_313046
