It advocates feasibility to designer or construction executor to investigate the stability of on structure before construction may be solve any trouble .design engineer and responsible of subway structure can obtain important findings about structure stability and equipment required to protection d, wry construction .4 stations include: Fahmideh, Baghmishe , Abbasi square , Azad university are located in line 2 Tabriz subway. Fahmideh station is located in commercial area and bagmishe station in fish market , Abbasi station in Abbasi square and Azad university station. There are several parameters effective in stability of these stations include of site geological condition , soil geomechnaics structural element characteristics , traffic loading , soil & structure displacement and ground subsidence. Regard to amount of these characteristic and application of the in F.E.M, it was analysis aborementened stations stability with ABAQUS the analysis were completed in 2 status ( one status for 3-story concrete underground station of Fahmideh , Bagmishe & Abbasi another station were taken for 2- story concrete station of Azad university station).It, also was accomplished analysis with 4 set of acceleration records for each model. The records were related to North-ridge , Kobe and Chi-Chi Taiwan as a near field earthquake and Imperial Valley as a far field .The records were scaled to Tabriz seismic condition then were used in analysis. The response of displacements , ground subsidence above station , sheer and axial forces and stresses were determined and presented in graphs.
