Description

technical field

[0001] The invention relates to the field of structural health monitoring of road-bridge tunnels, in particular to a monitoring and early warning device for road-bridge tunnels. Background technique

[0002] Most of the road-bridge tunnel structure monitoring sensors in the related art cannot predict the remaining life of the road-bridge tunnel structure according to the monitored data. This defect causes road-bridge tunnel structure maintenance personnel to judge the data fed back by sensors through their own relevant experience, which reduces the timeliness of road-bridge tunnel structure monitoring and greatly increases the workload of road-bridge tunnel structure maintenance personnel. Contents of the invention

[0003] In view of the above problems, the present invention provides a monitoring and early warning device for road, bridge and tunnel.

[0004] The object of the present invention adopts following technical scheme to realize:
