In order to promote economic development,a certain city has formulated a highway construction plan.In order to meet the huge demand for materials for highway construction,a widely distributed soil rock mixture is specially used as the filling material for highways.However,due to its non-uniformity and anisotropy,the engineering mechanical properties of soil rock mixtures are complex and difficult to understand,resulting in a lack of sufficient understanding of the strength and stability of the highway subgrade they construct.A clear understanding of the influence mechanism and factors on the strength and deformation of soil rock mixed fill roadbeds is of great significance for guiding on-site construction.Based on this,this article analyzes and verifies the physical and mechanical properties of soil rock mixtures and the stability of road-beds through on-site sampling,combined with indoor direct shear tests and numerical simulations.
