Analysis on the influence of shaft to train wind in high-speed railway tunnel
摘要
Abstract
According to the three-dimensional incompressible Navier-Stokes equations and the standard k-εturbulence model, take a tunnel with shaft into consideration, and establish a tunnel-shaft-train-air 3D numerical model, the speed of train is 350 km/h, and the time-history variation rules and space distribution characteristics of train wind in crossing region of high-speed railway tunnel are studied, the influence of the shaft area, length, and cross angle on train wind are analyzed, and the most unfavorable situation of train wind in high-speed single or double line tunnel are judged. 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.关键词
