Method of horizontal push-shear in-situ test is introduced briefly. And calculation formulation is presented according to limiting equilibrium theory. The shear strength parameters internal friction angle? and cohesive strength c of coarse-grained soil compacted subgrade in S325 highway are obtained by three field horizontal push-shear in-situ tests. And its rationality is evaluated. The results provide necessary base for optimum design of retaining walls.
