One of the most challenging issues encountered by engineers is the construction of Received in revised form 3 August 2013 subway stations as large underground spaces at shallow depth with soft surrounding soils. In this paper, Accepted 1 September 2013 Naghshe Jahan Square subway station located in Isfahan, Iran, has been simulated by geomechanical finite difference method (FDM). This station is located under important historical structures. Therefore, Keywords: the ground displacement and surface settlement induced by the excavation of the subway station should Subway station be strictly controlled. Many of such problems are affected by selected excavation method.
