| Abstract: | In this paper the physical model for coupling the dissipation and accumulation of the dynamic pore pressure is established and the finite element procedure is programmed. The efficiency of the sand pile in dissipating the dynamic pore pressure in the foundation of the Yuanping-Taiyuan Highway was estimated with the theoretical approach. |
