Background The subway is used as an urban core traffic carrier, the daily passenger traffic is over ten millions of times, and the tunnel structure safety is directly related to public travel safety. Along with the increase of the operation years, the factors such as long-term dynamic load, environmental corrosion, geological change and the like of the train lead to gradual manifestation of diseases such as tunnel lining cracking, ballast bed settlement, track deformation and the like, and the potential threat to structural safety is formed. Currently, subway tunnel monitoring mainly relies on static detection and manual inspection modes in a shutdown period, and although the problem of partial structural degradation can be covered, the core disadvantage is that dynamic safety risks in a train running state cannot be captured. The existing static monitoring equipment can only collect data in a night outage period, and cannot reflect instantaneous deformation, vibration response and stress change of a tunnel structure under the action of dynamic load of a train, and the dynamic response is just a key cause of sudden accidents such as lining fatigue cracking, ballast bed plate void, track geometric shape and position mutation and the like. For example, when a subway in a certain city is in a long-term vibration of a train, the ballast bed plate is not found out in time, and the geometric deviation of the track is finally caused to exceed the standard, so that the train is braked urgently, and in a similar case, the traditional static monitoring cannot capture a dynamic stress peak value in real time, so that structural damage cannot be early warned in advance. In addition, the manual inspection efficiency is low, the subjectivity is strong, and continuous monitoring of the whole period and the whole area of the tunnel is difficult to realize, so that potential safety hazard discovery is delayed. Therefore, it is necessary to design an intelligent monitoring device for deformation of a building for tunnel construction.
