TUNNEL HAVING STEEL RIB OF CONCRETE FILLED TUBE (CFT) STRUCTURE, AND CONSTRUCTION METHOD FOR THE SAME
Provided are a tunnel equipped with a steel rib of a concrete filled tube (CFT) structure and a construction method thereof, capable of increasing strength in comparison with the existing lattice girder by forming a steel rib used in tunnel construction with a CFT structure and installing on the tunnel excavation surface, improving constructability in a tunnel face due to a light weight, reducing a rebound amount when placing shotcrete in a space of a tunnel excavation surface and a CFT rear surface unit, significantly lowering space unfilled possibility, completely integrating the CFT and the shotcrete which do not generate a joint, and improving shock resistance and lateral resistance of the tunnel by using the CFT as the steel rib with excellent energy absorbing capacity.
