Bolting and shotcreting are commonly used in slope treatment. The retaining surface is made of plain concrete or reinforced concrete, which consumes a large amount of building materials and is expensive. Gray concrete is not in harmony with the surrounding environment, because highway slopes often require environmental awareness. In this paper, a new ecological slope compound retaining form of “bolting + geo-grid slope + green spray on borrowed soil” was presented and used over an experimental section. Calculation indicated that the slope stability and the anchor bearing capacity all meet the design requirements. The test section anchor rod adopted the GFRP anchor rod, the area is 100m2. After construction, compared with the traditional soil nailing wall concrete surface layer and lattice beam anchor bar retaining form, this form has the advantage of quick construction, economic application, which can be used to reinforce the slope and have green environmental protection function.
