Abstract: Construction of the tunnel and the exploitation of transportation network the underground space form part of the infrastructure which becomes fundamental in large cities to treat the growing problem of mass rapid transit. The tunneling-induced volume loss of ground is an essential matter to estimate the behavior of settlement through construction and their effects on adjacent structures. The predictions of distribution and behavior of stresses and surface settlement by analysis of finite element. In this study, the prediction of the settlement caused by tunneling investigated by simulation model using the finite element method with Mohr-Coulomb depend on the case study data. The behavior of stress a round tunnel calculates and analysis the settlement during tunnel construction and compared with natural soil through various stages of construction of the tunnel. The result the behavior of stresses of the native soil and through stages of construction of tunnel using the Tunnel Boring Machines (TBM) where it shows variations of stress-depth curves between the native soil and stages construction of the tunnel for specified distances and surface settlement curve that is compatible with previous researchers.
