Application of GNSS monitoring technology in loess landslide monitoring

简要介绍GNSS实时变形监测系统的组成、工作原理。以晋城市某黄土滑坡变形监测的实例分析,介绍了该滑坡的基本情况,GNSS技术在滑坡监测应用中的方法、监测网的布设,通过对滑坡监测数据处理及分析,对所生成的位移变化曲线图进行解读,得出了该滑坡目前基本稳定、没有明显的变形趋势的结论,体现了GNSS实时变形监测系统在滑坡变形监测实际应用中的优势,为同类型黄土滑坡变形监测提供参考。

This paper briefly introduces the composition and working principle of GNSS (Global Navigation Satellite System) real-time deformation monitoring system. Based on the instance analysis of the loess landslide deformation monitoring example in Jincheng city, this paper introduces the basic information of the landslide, the application method of GNSS technology in landslide monitoring, and the layout of monitoring network. Through the processing and analysis for landslide monitoring data, and the interpretation of the generated displacement change curve, it is concluded that the landslide is basically stable and has no obvious deformation trend. This paper reflects the advantages of GNSS real-time deformation monitoring system in the practical application of landslide deformation monitoring, and provides a reference for the same type of loess landslide deformation monitoring.
