This paper presents a finite element analysis to investigate the behavior of the piled raft-tunnel system in rock and sand soil. Abaqus CAE finite element program is used to modeled and analyze the piled raft-tunnel system. Safety is a sign that it is
focused on the service life of a traffic tunnel. It has affected the stresses and displacements of piled rafts of tall buildings. It has been
analyzed with the sandy soil model, intact rock model, and debris rock model. The model conducted of the group (1×2) piled rafttunnel, the clearance distance (H) is 130 mm from the pile tip to the top of the surface of the tunnel and the pile length (L) is 200 mm.
A square cross-section of the tunnel is (100 × 100) mm acted on along the z-axis of model direction and it has a thickness of 2 mm.
The vertical distance of the pile group base is 5 mm. Sandy soil model effected with a small value of stress 0.01809 MPa and high value of displacement 0.03844 mm otherwise in intact rock model and debris rock model gained the larger value of stresses and little value of displacements.
