Abstract Research purposes: In order to make the aerodynamic force of trains smaller and the construction of wind-break wall with good economics.
Research method: The numerical simulation calculation is carried out to the aerodynamic force of the train under wind-break wall with two dimension incompressible viscous N-S equations, when the cross-wind speed is 35.1m/s, the height and position of wind-break wall and the height of embankment are different.
Research results: the best height and position of wind-break varying with the height of embankment is established.
Research conclusion: The best height of wind-break wall is decreasing with the increase of height of embankment, and the extent is smaller. While the best position of wind-break wall has a little change from 3.4 meter to 3.5 meter basically.
