            Ceintuurbaan Station, North/South Metro Line
          
        
        
          With its length of 230 m, depth of 30 m and average width of 11 m, Ceintuurbaan is the narrowest
        
        
          station of the North/South line. Its great depth made it necessary to support the combination of
        
        
          diaphragm and retention walls in both the construction and final phases. Therefore, permanent steel
        
        
          struts are installed and prestressed. These struts are designed to bear the horizontal loads and
        
        
          minimise the deflection of the walls during the operational phase. The 3D model made it possible to
        
        
          analyse the behavior of the structure in the construction stages and to anticipate critical situations.
