Abstract：The cutting was a common roadbed cross-section in traffic lines, and it is more prone to wind-induced snow disasters than embankments due to cross-section characteristics . In order to provide suggestions and references for the cross-section design and the prevention and control of wind-blown snow disasters. Wind tunnel tests and numerical simulation methods were used to study the wind-induced snow accumulation processes on all-cuttings under different wind speeds. The influence of wind speed and cutting opening form on the snow distribution and accumulation process were analysed, and the ability of different cuttings to resist snow disasters was evaluated based snow accumulatio and snow depth on the road. The results show that when the slope of the upwind side slope is greater than that of the downwind side slope, the snow on the cutting road is the least and the snow depth on the road is the thinnest; wind speed and duration are important factors on snow accumulation,and increasing the wind speed and increasing the duration will aggravate the snow on the road; Changing the cutting slope has limited effect on reducing the snow on the road, and other prevention measures need to be set to reduce the snow disasters caused by snow drift.
