Keywords:Tunnel Deformation Survey, Heaving, Potential Geology, Leveling, Inner Space Displacement Measurement, Ground Sample Testing

In this study, the type of bedrock that causes the deformation in the tunnel with heaving is identified, and the method of deciding the countermeasure area in sections with the same rock type by creating the “Evaluation Method of the Expansion (Draft)” is proposed.
