基于磁定位技术的滑坡监测试验研究

滑坡的监测主要包括2个方面,即地表位移监测和深部位移监测。深部位移监测能够直观反映滑坡的内部状态,是滑坡监测技术的研究重点。针对目前深部位移监测技术存在的诸多问题,提出了一种新型的滑坡深层位移监测技术,即一维磁定位技术。采用理论和试验相结合的分析手段,探索这一技术在滑坡深部位移监测中的可行性;通过对磁定位相关理论的分析,推导出了深部位移与磁感应强度之间的理论关系式,并采用试验验证了这一关系的正确性。最后随机选取了8个验证点进行定位验证试验,结果证明了一维磁定位技术在滑坡监测中的可行性,其定位精度能够达到mm级,满足滑坡监测精度要求。

Experimental Research of Landslide Monitoring Based onMagnetic Positioning Technology

At present, landslide monitoring mainly involves two aspects: surface displacement monitoring and deep displacement monitoring, of which the latter could directly reflect the internal state of landslide, which is a research focus of landslide monitoring technology.In view of the problems of deep displacement monitoring technology, one-dimensional magnetic positioning technology was proposed in this article.In association with theory and experiment, the feasibility of using the technique in deep displacement monitoring of landslide was explored, and the relationship between deep displacement and magnetic induction intensity was deduced and verified by experiments.Finally, eight random points were selected to carry out position verification experiments.Result proves that it is feasible to apply one-dimensional magnetic positioning technology in landslide monitoring, and its positioning accuracy reached millimeter level, suitable for the requirement of landslide monitoring.
