Tunnel periphery surface displacement real-time monitoring device

A tunnel periphery surface displacement real-time monitoring device belongs to the technical field of tunnel construction monitoring, which comprises a displacement transducer, a data acquisition device connected with the displacement transducer and a data processor which is connected with the data acquisition device, wherein the displacement transducer is an optical fiber type displacement transducer, and the optical fiber type displacement transducer comprises a strip base plate and optical fiber cables which are fixed on the upper surface and the lower surface of the base plate along the length direction of the strip base plate. The tunnel periphery surface displacement real-time monitoring device has the advantages of difficulty in damaging monitoring points, simple structure, low cost and free restrictions to the testing environment, such as the magnetic field, vibration, water, wind, visibility, particle content in air of monitoring places. The monitoring device not only can be applied in the constructi
