Continuous and accurate tunnel lining structure deformation monitoring device

The utility model provides a continuous and accurate tunnel lining structure deformation monitoring device, which is used for monitoring the deformation condition of a tunnel lining structure and comprises a tunnel, a displacement meter monitoring system and an optical fiber monitoring system. Wherein the displacement meter monitoring system is circumferentially arranged along the inner side and the outer side of the tunnel, and an optical fiber sensor in the optical fiber monitoring system is embedded in a tunnel lining structure. The continuous monitoring device adopted by the utility model can realize continuous monitoring of the circumferential deformation of the tunnel lining structure in the test process, and compared with a traditional strain gauge monitoring mode, the continuous monitoring device has the advantages of wider measurement area coverage, more concise layout and more stable monitoring. 本实用新型提供了一种连续和精准的隧道衬砌结构变形监测装置，以用于监测隧道衬砌结构变形情况，该监测装置包括隧道、位移计监测系统和光纤监测系统。其中，位移计监测系统沿着隧道的内侧和外侧位置周向布置，光纤监测系统中的
