Abstract
In this study, a series of finite element numerical analyzes were performed considering the pavement thickness and traffic load for the purpose of stability analysis on the cavity ground. In order to verify the validity of this numerical method, the previous numerical analysis was used to simulate the mechanical behavior of cavity ground, and the results were compared and analyzed. Also, from the numerical results, it was possible to confirm the dynamic behavior of the ground by confirming the change of ground void ratio, surface settlement, and shear stress, and using the relationship between stress ratio, non-destructive depth and surface settlement, the safety of the was analyzed. As a result, as the pavement thickness decreased and the traffic load increased, the non-destructive depth and the overall stability of the ground decreased with the increase of surface settlement.
