摘要

现有边坡深部变形监测仪器易受雨水、泥石流、滚石等环境的影响，仪器布设较繁琐，且无法监测边坡深部滑移的中后期变形。基于磁场定位理论，采用磁性物质制作智能石头，在边坡深部布置智能石头，通过智能石头和全张量磁力梯度仪建立边坡深部大变形监测系统。基于磁场梯度张量缩并定位对智能石头进行三维定位，实现边坡深部的中后期大变形监测。针对全张量磁力梯度仪的精度和地球磁场梯度的影响，由三维磁感应强度和磁场梯度的分析，其有效监测距离为35 m；在磁场定位试验中，监测精度为0.06 m。可为磁测在边坡深部大变形监测的进一步研究和应用提供参考。

Abstract

The existing slope internal deformation sensors are easily influenced by rainwater

mud-rock flows

rolling stones and other environmental factors. The arrangement of equipments is not convenient for the internal deformation monitoring; and the internal deformation monitoring can not be realized by the present technology during middle and late periods of sliding. Based on the magnetic localization theory

the smart rock is fabricated with magnetic label; and smart rock is embedded in the deep part of slope. So the slope internal large deformation monitoring system is established with the combination of smart rock and full tensor magnetic gradiometer. The localization by magnetic gradient tensor contraction is used to track the three dimensional motion of smart rock in order to realize the slope internal large deformation monitoring. With regard to the precision of full tensor magnetic gradiometer and influence of earth magnetic gradient

the effective monitoring distance can reach 35 meters by the analysis of magnetic strength and magnetic gradient. In the experiment

the deformation monitoring accuracy is 0.06 meter

which can be used as reference in the further study and practical engineering monitoring.
