Abstract
Accurate exploration of the risk factors of the ground subsidence is needed to predict and evaluate the subsidence of the surrounding ground due to the excavation of the ground. In this study, we analyzed the distribution of soil relaxation area by analyzing the behavior around the ground excavation site and simulated the GPR exploration under various conditions. As a result, Although there are some differences according to the water content, distribution of the strata and the distribution of the relaxation region were confirmed in the unsaturated soil, and it was found that there was a difficulty in the GPR exploration in the saturated soil.
