Permanent excavation interaction and adjacent building under earthquake (Case study: Entrance ramp of the city train and hamyari-shahrdari building)

Deep excavation have a direct effect on stresses and strains of surrounding soil, and it leads to the change in static and dynamic response of adjacent structures of the excavation. In this study the effects of urban rail ramp permanent excavation on Hamyari response, has been investigated. Consider...
