Taking the shallow channel wind acceleration embankment on the national highway G207 in Xilingol League， Inner Mongolia， as the research object， the section composition factors， wind speed and flow field， and snow cover were observed for three years. The research results indicate that when the airflow passes through the section of the shallow channel wind acceleration embankment， a deceleration zone is formed at the foot of the windward slope， the leeward curved surface of the shallow channel， the deepest part of the shallow channel， the foot of the windward roadbed slope， and the foot of the leeward roadbed slope， resulting in the accumulation of snow particles. At the upper part， top， shallow channel， windward curved surface， and windward shoulder of the accelerating embankment， a growth zone is formed， causing snow particle deposition. Through regression analysis of the five main parameters of the shallow channel wind acceleration embankment， including leeward chord length （L₁）， windward chord length （L₂）， shallow channel depth （H）， chord depth ratio （L/H）， and leeward chord length/windward chord length ratio （L₁/L₂）， it was found that the most important influencing factor on whether snow accumulates on the road surface is the leeward chord length/windward chord length ratio （L₁/L₂） of the shallow channel wind acceleration embankment. At the same time， the study found that whether snow accumulates in the channel of the shallow channel wind acceleration embankment is not related to the chord depth ratio of the shallow channel wind acceleration embankment. Degree of snow on the road surface varies depending on the cross-sectional parameters， and in practice， it is possible to determine whether snow has accumulated on the road section where the shallow channel wind acceleration embankment is located by calculating relevant parameters.
