Abstract: Due to the engineering characteristics of the tunnel structure, there are potential safety hazards under complex geological, hydrological and climatic conditions. It is necessary to carry out monitoring and research on the tunnel cracks that affect the service safety of the tunnel, to grasp the uncompacted voids behind the tunnel cracks in real time, and to predict and warn the tunnel structure diseases in advance. In this paper, aiming at the crack diseases that appear in the regular detection of tunnels during the operation period, we explore how to efficiently obtain and dynamically grasp the development and evolution trend of the non-compact cavity behind the tunnel structural cracks in real time. A non-compact cavity monitoring system based on distributed optical fiber is recommended to comprehensively improve the service quality and service life of the tunnel, promote the deep integration of digital intelligent technology and tunnel monitoring management, and provide strong support for tunnel intelligent scientific monitoring and maintenance management.
