Abstract

Today, the foundation excavation for the construction of high-rise buildings, basements, parking lots, etc. is required. Because space is limited in urban areas. The aim of this study is to answer this question is that transformation that drilling in the Line 2 subway (Case Study) creates significant or negligible. Tunnel floor deformation and deformation from 62 mm to 113 mm from 16 mm to 58 mm Bore tunnel with the size of the underground drilling of the horizontal distance is variable.Today, the foundation excavation for the construction of high-rise buildings, basements, parking lots, etc. is required.
