Slope deformation and instability monitoring system and method based on self-adaptive scale distance

Abstract

The invention discloses a slope deformation and instability monitoring system and method based on self-adaptive scale distance. The system is formed by magnetic sensing elements, a full tensor magnetic gradiometer, a data transmission system and a data control system. The monitoring method overcomes the problem that a geotechnical model having subjective experience needs to be combined in deep slope deformation and instability monitoring; and scale distance is adjusted automatically to adapt to different displacement dimensions in various deformation stages of a slope under the condition of needing no slope geomechanical parameters and mechanical model, so that deformation in different stages can be measured accurately, and deep slope deformation and instability monitoring and early warning are realized.
