The invention discloses a railway turnout movable steel rail displacement monitoring device, a monitoring method and an evaluation method, and the device comprises a displacement sensing device, a displacement monitoring device and a fiber bragg grating demodulation device. The displacement sensing device is mainly used for sensing tiny displacement of a track, the displacement monitoring device is mainly used for tracking and measuring a displacement value in real time, and the fiber bragg grating demodulation device is mainly used for recording and feeding back a displacement state. The system has the advantages of electromagnetic interference resistance, long-distance transmission and the like, the multiplexing and networking capabilities of the optical fiber displacement sensing technology are relatively strong, and compared with the traditional electrical test technology, the system has the characteristics of electrical insulation, corrosion resistance, no drift and the like, and can meet the long-term monitoring requirements of high-speed railways. And the method has important practical significance on safety monitoring and maintenance of the railway. The invention further constructs an evaluation method for the displacement of the movable switch rail/point rail of the high-speed turnout, and real-time data and on-site basis are provided for normal operation and safety maintenance of a railway.
