摘要： PROBLEM TO BE SOLVED: To detect local small extension by laying optical fibers on a structure by an arbitrary number of returns in an arbitrary interval. SOLUTION: An optical fiber sensor 10 is laid with optical fiber 11 on a tunnel wall by an arbitrary number of turnarounds in an arbitrary interval. Here, the optical fiber 11 is laid on a belt shape steel plate 12 of which width is determined to have marging for the radius of curvature of the optical fiber, so as not to affect the distortion measurement value by the attenuation of transmitting light quantity due to the bend of the optical fiber 11. By this, when the tunnel inner wall extends or contracts, the optical fiber 11 of the optical fiber sensor 10 extends or contracts according to this. The extension and contraction of this optical fiber 11 equivalently extends or contracts to the optical fiber 11 corresponding to a total of 5 pieces of fibers of 2 m for every 40 cm interval laid in the interval L of a unit length. This is applicable not only to distortion of tunnel inner wall but also to the measurement of deformation of various structure, for example, a structure having a curvature surface.
