Description
technical field [0001] The invention belongs to the technical field of anti-scouring experiments of ecological coiled materials, in particular to an experimental device and an experimental method for testing the anti-scouring performance of ecological coiled materials. Background technique [0002] Anti-scouring design is an important part of slope stability and protection design. Scouring will cause soil erosion and pollute the environment. A large amount of sediment will be accumulated at the foot of the slope or on the roadway, hindering road drainage and even affecting driving safety. After the slope is protected by vegetation, the vegetation can reduce the loss of water and soil, reduce the intensity of rain erosion, and improve the bonding between particles inside the soil, which is beneficial to the stability of the slope. [0003] The scouring effect of different rainfall intensities and precipitation areas on ecological plant slopes requires the design of an anti-sc...
