Experimental Study on Erosion Stability of Thick Layer Base Material Spraying Bio-Slope-Engineering

The erosion stability of base material mixture is one of the important indices of evaluating thick layer base material spraying bio-slope-engineering. Based on artificial rainfall experiments, the effect of base material mixtures with different compositions on its erosion modulus is studied. The results show that the erosion stability of base material mixture is decreased by the increase of planting soil and the reduction of organic materials and fibers, but is increased by slope vegetation.
