Abstarct: Nowadays, due to the increasing expansion of urban areas, increasing the density of surface structures and lack of space for intra-urban transportation, the necessity of the implementing underground structures such as underground tunnels and metro stations in urban areas is essential. One of the most important factors in implementing of deep metro station in urban areas is the appropriate method of excavating, which has a significant effect on the stability of surrounding spaces of the tunnel during excavation, surface settlements caused by excavation, as well as the long-term stability of the excavated space (metro station). One of the main goals of tunnel designers is to ensure that the tunnel does not fall during and after the implementation as well as the lack of inappropriate deformations in surface structures. So, recognizing and investigating the interaction of tunnels, soil and surface structures are very important and should be considered. Therefore, in the present study, we studied these interactions and compared them with monitoring values of the settlement at the Shohada Square metro station, line 2 city train, in Mashhad. This study aimed to investigate the effects of underground excavation on behavior of soil. To achieve this goal, researches in this field were reviewed at first. Most of these studies are done using the numerical simulation as well as the finite element method software packages. In a few cases, the verification of the numerical model is done by comparing the results of the model with the instrumentation results of the actual excavated tunnel. Since previous studies have often been investigated settlement caused by mechanized excavation or no comparing with the results of instrumentation, in the present study the surface settlement caused by underground excavation and its comparison with two and three-dimensional models after the excavation of the Shohada Square metro station, line 2 city train, in Mashhad were investigated. Also, according to the positive and negative aspects of different methods as well as available facilities, a numerical simulation using two finite element method software packages, PLAXIS 2D ver. 8.6 and PLAXIS 3D, was used in this study. Using the numerical model, changes in the different surfaces related to tunnel and soil around the tunnel were investigated.
