Study on the high-filling's influence of the force-deformation on the pile frame structure embankment on the soft soil

The deformation of soft soil foundation is characterized by time and nonlinearity. With the increase of filling on the embankment, the pile foundation not only bears the upper load, and is also affected by the lateral extrusion and negative friction of deep soft soil. Especially when the soil is in an elastic state, the relationship between deformation and load is nonlinear. In this paper, finite element software is used for numerical simulation to explore the force and deformation law of the pile foundation frame structure under the action of high fill.
