The scale and depth of excavation necessary for building the structure has been increased in line with concentrated urbanization and the effect on underground structure by varying groundwater level is also increasingly growing, which require advanced ground deformation prediction technology depending on variation of groundwater level. Particularly, as unconsolidated sediment or soil repeats saturated-unsaturated cycle, volumetric water content in voids of soil varies accordingly. In this study, a complete grid-base groundwater flow analysis model which combines the 3D groundwater analysis module for saturated and unsaturated zone was used. To evaluate the applicability of the model used, modeling was conducted on assumption of the scenario. In particular, a conceptual model incorporating the rock mass and geological structure that shall be considered in predicting the groundwater behavior and ground deformation by excavation was adopted.
