FUNCTION OF SAND FENCE PLACED IN FRONT OF EMBANKMENT

[摘要] In order to find the optimum sand fence porosity and the best position for placing a sand fence in front of an embankment, a series of experiments were conducted in a large wind tunnel. The results obtained were that a fence with 40 % or 50 % porosity should be placed at a distance between 15 H and 20 H in front of the embankment, where H is the fence height.
