Abstract：Research purposes: Snow drifting is a main type of disaster in the cold region，which threatens transportation badly，SO doing the researches on the snow drifting disaster to embankment has theoretical and real significances to the transportation construction in the snow disaster area．
Research conclusions: In this paper，the flow field of wind and snow in embankment construction is simulated with the ANSYS software of FEM and the analyses of influences of subgrade height，side slope ratio and change of background wind velocity on the wind velocity of embankment are made to section of embankment．The results show the simulated values When the embankment height arrives at the certain level，the velocity can effectively reduce the road surface snow drifting．embankment design
