Numerical modeling of ground settlement control of large span underground metro station in Tehran Metro using Central Beam Column (CBC) structure

► Central Beam Column (CBC) structure is introduced in a staged construction of a large underground. ► Settlement control over an underground Metro station in Tehran is investigated using 3D FE analysis. ► Cases of system with, without CBC and of an improved ground by consolidation grouting are comp...
