Thesubloading-friction model is the unconventional elastoplastic friction model which allows the sliding displacement due to the traction rate below the sliding surface. It is capable of describing a gradual progress of relative tangential displacement with the increase of tractions. In this article, the soil-pile interaction problem for the monotonic and cyclic loading under the plane strain condition is analyzed by the finite element program incorporating the subloading- friction model. It is revealed that the sliding displacement due to the traction rate below the sliding surface gives the influence to soil-pile interaction behavior.
