Abstract: It is a quicker, better and more economial way to research snow drift and its control by modelling experiments in the wind-tunnel. The exact similitude is required for performing modelling test. This paper summarizes the similarity criteria and 10 parameters, as well as results got from the test in wind-tunnel of self-sumulation.Accumulation of snow drift occurs in boundary layer separation areas where the eddy resistance increases rapidly. In the case of roads, different fields of flow on different land-forms near the roadbed may give rise to different processes and quantities of drifting snow. Structure of flow fields and drift accumulation on cut and tunnel are rather complicated, so their snow control is more difficult than on other roadbeds. This paper reports the methods and problems in need of special attention, which is helpful in choosing courses, roadbed design and prevention of drifting snow in places with cut and tunnel.
