The mechanical effect of plant roots on soil is an important factor in improving the erosion resistance of slopes, and the relevant research on the impact resistance of plant roots under water flow at home and abroad is in a blank spot. In this paper, the common soil and water conservation plants tall fescue and dogtooth roots were selected as the research objects, and the jet erosion test was carried out on the slope of the plant model, and the erosion failure mechanism of the root slope of different species of plants was compared. The main conclusions are as follows: the variation law of the average erosion depth ΔDAE of high fescue slope, dogtooth root slope and plain soil slope under different working conditions is similar and consistent, and it increases exponentially as a function with the increase of erosion flow velocity and linear function with the increase of erosion angle. The average erosion depth under various working conditions was generally as follows: high fescue< dog tooth root< plain soil; The average erosion depth of high fescue at each flow rate decreased slightly ΔDAE slightly greater than that of dog tooth root. When the scouring angle was fixed, the ΔDAE of each angle was the largest when the flow rate was 1.6 m/s, and the flow rate was higher than 1.6 m/s, and gradually decreased. When the erosion flow rate is constant, there is a decreasing tendency ΔDAE increase with the increase of the scouring angle.
