The elastic and viscoplastic model was used to simulate the stress and strain characteristics of the roadbed and the soft soil foundation. The basic equations of the dynamic finite element were established. The finite element analysis and calculation of the interaction between the road surface and the ground under the load of the aircraft were carried out. Surface and foundation co-acting deformation characters
