The 3D Vegetation Net Slope Protection technology combines the benefits of geotextile nets and vegetation slope protection, effectively addressing the protection issues of rocky and steep slopes.

Three-dimensional Vegetation Net Slope Protection refers to a new technology that constructs a self-growing protection system on the slope surface by utilizing active plants combined with engineering materials such as geosynthetic materials. It reinforces the slope through the growth of plants. Based on the characteristics of the slope terrain, soil quality, and regional climate, a layer of geosynthetic material is covered on the slope surface, and a variety of plants are planted at certain combinations and intervals. Through the growth activities of plants, the purpose of reinforcing the root system and preventing erosion of the stems and leaves is achieved. After treatment with ecological slope protection technology, a dense vegetation cover can be formed on the slope surface, with a tangled root system in the surface soil layer, effectively inhibiting the erosion of the slope by heavy rain runoff, increasing the shear strength of the soil mass, reducing pore water pressure and the self-weight of the soil mass, thereby significantly improving the stability and erosion resistance of the slope.

The anti-erosion effect of vegetation is achieved through its three main components: 1) The growth layer of plants (including sepals, sheaths, leaves, and stems), which prevents the direct erosion of the slope surface soil by rainwater through its dense coverage, reducing the scouring energy of heavy rain runoff and the speed of surface runoff, thereby reducing soil loss; 2) The humus layer (including the interface between the leaf fall layer and the root stem), which provides a protective layer for the slope surface soil; and 3) The root layer, which reinforces and anchors the slope surface soil, providing mechanical stability. Generally, during the early stages of plant growth, the individual plant roots are loosely intertwined without a sprawling root system, making them prone to separation from the soil layer and failing to provide protection. The application of a three-dimensional mesh is to enhance the effectiveness of these three aspects to achieve more thorough shallow protection. First, within a certain thickness range, it increases the protective performance and mechanical stability; secondly, due to the presence of the three-dimensional mesh, the large root system of the plants is connected to the mesh reinforcement, forming a plate-like structure (equivalent to reinforcing the slope surface soil), thereby increasing the tensile and shear strength of the protective layer, limiting the expansion of the "gradual destruction" phenomenon (erosion can directly damage individual plants, with the damaged area increasing over time) and restricting the occurrence of shallow surface sliding and heaving of the slope.
