基于GNSS的抚顺西露天矿北边坡变形监测方法研究

Study on the Slope Deformation Monitoring Methods Based on GNSS in the North of Western Open Pit in FuShun

以抚顺西露天矿北边坡沉降变形监测分析为目标,在探讨了GNSS用于边坡变形监测的方法优势及特点的基础上,对变形监测设计方案,尤其是对监测点的布设、监测数据的采集、数据处理方法、监测结果的分析进行了深入研究。根据三年的变形监测成果分析,给出了抚顺西露天矿北边坡变形范围、沉陷变形速率、以及GNSS变形监测的优势和应注意的问题,对GNSS在露天矿边坡监测中的广泛应用具有指导意义。

In the paper,the author studies the design of deformation monitoring,especially the layout of monitoring points,the monitoring data acquisition,data processing methods and the analysis on the monitoring results in-depth in the basis on seriously discussing the advantages and the characteristics of GNSS methods for slope deformation monitoring according to the slope deformation monitoring analysis in the north of western open pit in Fushun.According to the three-year analysis results of deformation monitoring,the author gives the slope deformation range,the subsidence deformation rates,as well as the advantages and the problem using GNSS deformation monitoring.It has been guiding significance for GNSS widely used in slope monitoring in open pit.
