Notes:
The sand cover is the main form of sand disaster for the desert highway induced by thewind-blown-sand flow over the highway. As a kind of two-phase flow of air and sand, it is necessaryto study the physical principle and the mode of its migration. The Smoothing Particle Hydrodynamic(SPH) method is adopted to simulate the movement of the wind-blown-sand flow. A two dimensionalmodel of the sand cover for desert highway with embankment is built with SPH method. Thenumerical simulations are carried for different embankment height to investigate the sand coverdistribution on the road surface of desert highway. The results show that the migration of sand withwind blow can be well simulated using SPH method and the embankment height is an importantfactor for controlling sand cover disaster of desert highway
