| Abstract |
Based on the theory of solid porous media with pores, considering the interaction between soil particle phase, pore liquid water phase and pore ice phase in saturated frozen soil, the dynamic response of two-dimensional saturated frozen soil foundation under moving load is studied. By introducing the potential function and using the Helmholtz principle, the solutions of the displacement and stress of each phase of saturated frozen soil under moving load in the frequency domain are obtained through coordinate transformation and Fourier transform. Finally, the numerical results are obtained by the fast Fourier transform (FFT) method. The effects of load moving speed, temperature, porosity, cementation parameters, load frequency and contact parameters on the dynamic response of two-dimensional saturated frozen soil foundation under moving load are analyzed in detail. The calculation results show that the changes in porosity and cementation parameters have a significant effect on the real magnitude of vertical and horizontal displacements of the foundation surface under moving loads. |
