摘要： PROBLEM TO BE SOLVED: To provide a concrete structure which is low in cost and high in strength, and can prevent concrete fracture.
SOLUTION: A segment 1 or the concrete structure is formed like an almost arcuate plate consisting of steel members 2 and concrete 3. The plurality of segments constitute a cylindrical wall body by being connected to each other in a circumferential and axial directions. The steel member 2 includes main steel members 10, 11, 12 almost arcuately curved and arranged along the tunnel circumferential direction, and both longitudinal edges of each of the main steel members 10, 11, 12 are exposed to contact surfaces 4 for connecting the segments together in the tunnel circumferential direction. Thus, when the contact surfaces 4 are connected together, both the edges of each of the main steel members 10, 11, 12 are connected together.
