PROBLEM TO BE SOLVED: To provide a structure displacement/deformation detection system using an optical fiber cable capable of easy installation, capable of providing a measurement device economically as well as capable of detecting the occurrence of relative displacement/deformation of the shore protection structure and its occurrence position and measuring the relative displacement, and also capable of precisely detecting the amount of the deformation while using the optical fiber sensor for communication use, generally used for the linear shore protection structure. SOLUTION: The structure displacement/deformation detection system using the optical fiber sensor is provided with the optical fiber laid on the detection object, the displacement/deformation sensing device and a displacement/deformation management device. Wherein, the displacement/deformation sensing device is characteristically composed of the sensing part formed with at least≥2 stopping part and a loop part and a detection signal, and a displacement/deformation management device is provided with a light intensity measurement device or a OTDR (Optical Time Domain Reflectometer).
