Deformation monitoring system and method for concrete face rockfill dam

The invention relates to the field of safety monitoring, and discloses a deformation monitoring system and method for a concrete face rockfill dam, which is used for improving the accuracy of a deflection monitoring effect and detecting disengaging deformation under a concrete face. The system comprises a processor, a detector, a walking pipeline, the concrete face and a padding layer, wherein theconcrete face is arranged on the padding layer; the walking pipeline is attached to the concrete face, and is installed in the padding layer from top to bottom along the slope surface of the concreteface rockfill dam; during deformation monitoring, the detector is used for crawling along the walking pipeline and sending crawling trajectory information to the processor; and the processor is usedfor calculating and analyzing the crawling trajectory information of the detector to obtain a deflection value of the concrete face rockfill dam, a disengaging value under the walking pipeline and andisengaging part. The deform
