In recent years, modern technology in the construction of tunnels using tunnel-boring machines (TBM) is implemented in the practice of civil engineering in large cities which significantly reduces the harmful effects of tunneling on the ground's surface. Construction of the tunnel becomes fundamental and the exploitation of underground space form part of the infrastructure to treat the growing problem of mass rapid transit in urban cities. The method of tunnel construction numerical modeling based on the finite element method is used to evaluate of the ground movement induce tunneling which is an essential matter to predict the settlement through construction and their effects on adjacent buildings. A method of surface settlement prediction is based on field data and results of construction phases numerical modeling. In this study, the prediction of the settlement caused by tunneling by simulation model using numerical method (FEM), with Mohr-Coulomb. This method involves determination of the following characteristics of displacement process: the distribution of displacements, the position of the point of the maximum settlement and the value of the maximum settlement, and strains in the trough. The developed method for calculation of the settlements and he 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 results show the behavior of stresses of the native soil and predication of surface settlement through stages of construction of tunnel using the tunnel boring machines(TBM).
