摘要： PROBLEM TO BE SOLVED: To provide a method for reinforcing a segment which bears a horizontal compressive force during the excavation of a shallow location and can be efficiently installed, and a reinforcing structure constructed by the method. SOLUTION: The structure 2 for reinforcing the segment 1 in a tunnel 3 reinforces the segment 1 which is annularly laid in the tunnel 3 bored by a shield machine 10 and covered with soil in low height. A horizontally-installed permanent beam 4 is provided in the segment 1. The rod-like permanent beam 4 is installed in the segment 1 in such a manner that its longitudinal direction is orthogonal to the axial direction of the tunnel 3. In this embodiment, the permanent beams 4 which comprise first and second permanent beams 4a and 4b installed in the inside lower and upper portions of the segment 1, respectively, are installed in segment rings 1b on a one-by-one basis, respectively.
