3D numerical simulation is adopted to analyze the dynamic response of highway under single loading circle,and to calculate the stress in the roadbed.By a series of triaxial dynamic tests,the relation between residual deformation of soft soil and numbers of loading cycles is proposed.On the basis of the above studies,a method is set up to calculate the residual deformation of soft foundation under vehicle load,and road surface settlements under different vehicle load are analyzed.
