NUMERICAL SIMULATION OF WIND-INDUCED SNOW ACCUMULATION IN ROAD CUTTINGS OVER TIME
Cut slopes are among the most severely affected roadbed types in wind and snow disasters.To provide reference for practical road section design and wind-snow disaster prevention,this study focuses on common cut slopes in transportation routes.Using the Mixture model in Fluent,the study simulates the two-phase flow of wind and snow and validates the simulation results.The research investigates snow distribution patterns in cut slopes dur-ing wind-snow disasters and compares the flow fields during the evolution of snow distribution.The findings reveal that the accumulation of snow in local protruding areas at the downwind slope of cut slopes is directly related to the formation of vortices inside the cut slope.The snow phase concentration inside the cut slope increases overall due to the accumulation of snow and changes in wind speed and flow field at different times.The maximum concentration of the snow phase appears near the top of the upwind slope.This research provides valuable references for predict-ing snow-related disasters in cut slopes and for setting parameters in numerical simulations of wind-snow two-phase flow.
