| Abstract: | According to the complexity of analytical solution achieved from the dynamic consolidation model,we considered the inertial stress and dynamic consolidation stress of the ground,and built the dynamic balance equation of the soil based on the 3D finite element method,and got the iterative format for the balance equation. After the numerical analysis for an instance, the rule of soil dynamic respond in the dynamic consolidation process is gained. It provided the valid method for the exact simulated analysis of the reinforce mechanism for dynamic consolidation. |
