Experimental Study of Influence of Grass Coverage on Runoff Shear Force of the Slope Surface

摘要：

　　Through outdoor artificial simulation test,the influence of the grass coverage on runoff shear force of the slope surface was studied.The results showed that the slope surface runoff shear force decreased with the increase of the grass coverage.In the experimental condition of 30° slope and 5L/min flow magnitude,runoff average shear force of the bare slope,low coverage and high coverage of the slope surface were respectively 0.9 Pa,0.5 Pa and 0.3 Pa.The fluctuation changing range along the riser and the test diachronic of the slope surface runoff shear force of all kinds of slopes decreased with the increasing of the grass coverage.
