Roadbed and pavement monitoring method and system based on distributed optical fiber three-layer burying
The invention belongs to the field of traffic engineering, and provides a roadbed and pavement monitoring method and system based on distributed optical fiber three-layer burying, and the technical scheme is as follows: burying packaged distributed optical fibers in a road structure; acquiring strain and temperature distribution change conditions along the distributed optical fibers based on the distributed optical fibers buried in the road structure; based on the strain along the distributed optical fibers and the temperature distribution change condition, structure settlement values of the positions where the optical fibers are buried in the pavement surface layer, the pavement base layer and the roadbed bottom are obtained through calculation; calculating and analyzing by combining the measured settlement values of the roadbed bottom and the pavement lower base layer to obtain a roadbed settlement value of the road, and calculating and analyzing by combining the settlement values of the pavement surface layer and the pavement base layer to obtain a pavement settlement value of the road; and comparing the subgrade settlement value, the pavement settlement value and a set threshold value, and obtaining a corresponding road safety early warning scheme according to a comparison result. And a feasible means is provided for road management departments to monitor road diseases and maintain roads.
