The negative skin friction will affect the bearing capacity of the pile.The process pile-driving is simulated as cylindrical cavity expansion based on ADINA and three-dimension Biot's consolidation theory.Soil around the pile is defined as porous media material.the dissipation of the excess pore pressure and the settlement of soil around the displacement pile after driving the pile are analyzed and some conclusions are obtained.In addition,the test results were compared and the FEM model considering Elasto-...
