Based on the solution of finite layer of Biot consolidation in the elastic media foundation, a finite layer finite layer solution of viscoelastic foundation is given using the elastic viscoelastic correspondence principle and the Laplace transform, and the program is compiled. The case study of elastic foundation settlement validates the correctness of the calculation method and program. With the increase of viscosity coefficient, the viscosity of the model plays a greater role, which is consistent with the creep change law of the selected viscoelastic model . Finally, the relationship between consolidation effect and viscosity effect is analyzed.
