PURPOSE: A truss structure for a tunnel is provided to obtain structural safety effects, allow a user to easily perform a tunnel maintenance work, and remove the interference of a structure installed in the tunnel. CONSTITUTION: A truss structure (100) for a tunnel comprises a horizontal truss member (110), a vertical truss member (130), and a reinforcing truss unit (150). The horizontal truss member is included in a single layer to avoid a fixture installed in the upper part of the inside of the tunnel. The vertical truss member is vertically connected to the horizontal truss member and is included in the single layer to avoid the fixture installed on the side of the inside of the tunnel. The reinforcing truss unit is formed to be able to protrude in order to reinforce a corner at which the horizontal truss member and the vertical truss member meet. |
