| Abstract | ||
| The present work is focused on the influence of shallow tunneling on the settlement of existed two storey building supported on different soil properties ranging from medium to stiff clayey soil that having young modules of "50,75 and 100 MPa". Eight locations of the tunnel center "diameter = 4m" were fixed below the building strip footing "width = 2m" at different depths and locations to determine the critical location of the tunnel at each depth. A total of 24 Finite element CAD "ANSYS" solutions were performed on the eight locations for each of the three types of soil. The results of the FEM analysis show that the effect of tunneling was to increase the surface settlement and creating differential settlement at the different locations and the critical location of the tunnel was when the tunnel center is located below the center line of the footing at both depths. | ||
