Abstract: | Based on ecological slope protection models by orthogonal tests, comparative experimental study of properties of slope protection through grass jetting on 3D geomat considered types of 3D geomat, density of grass seeds, types of soil and slope gradient are conducted under different rain intensity. The results show that the sequence of sensibilities for erosion modulus is density of grass seeds, slope gradient, types of soil and 3D geomat under the condition of simulating light rain, geomat can play a remarkable role to erosion modulus under the condition of simulating rainstorm, the erosion modulus for slope protection by grass jetting 3D geomat reduces 5 times than non protection natural slope. Equivalent cohesion of soil grass geomat compound decreases with the increase of depth, and curvilinear regression between equivalent cohesion and depth is cubic polynomial expression. Permeability coefficient of surface soil tends to increase with thicker geomat and bigger density of grassroots. |
