摘要： PROBLEM TO BE SOLVED: To provide a concrete-filled steel segment for improving economic efficiency of a tunnel lining body by integrating a filling concrete, which has been used as a substitute material for secondary lining, as a structural member.
SOLUTION: In the concrete-filled steel segment, vertical ribs 5 adjacent to joint plates 4 are respectively arranged as follows. Namely, the angle θ formed at an intersection of central axis lines extended from the central axis lines of vertical ribs 5, which are adjacent to each other at an interval in a peripheral direction of a tunnel, toward a center in the radial direction of a segment ring is made to be in the range of 10-25 degrees. The angle formed at the intersection of the central axis lines extended from the central axis line of the vertical rib 5 adjacent to the joint plate 4 and from the central axis line of the joint plate 4 toward the center in the radial direction of the segment ring is made to be the same as or smaller than the arrangement angle of the vertical ribs 5 adjacent to each other at an interval in the peripheral direction of the tunnel.
