Research on Slope Automatic Monitoring SystemApplication Based on GNSS

高速公路高边坡普遍具有较高的安全隐患,一旦发生失稳则会影响高速公路的安全运营。本文通过将北斗卫星导航定位、云解算、可视化等新型技术方法进行充分融合,构建基于GNSS的高边坡自动化监测系统,对某山区高速公路边坡位移变形进行实时动态监测,同时利用伺服全站仪对GNSS自动化监测成果进行检校,对比发现高边坡GNSS自动化监测系统在平面位移监测方面精度较高,垂直方向监测精度略低,但仍旧能满足边坡工程长期监测需求。相较于人工监测,高边坡GNSS自动化监测系统能够全天候实时动态获取边坡位移变形信息,利用高频次监测数据直观地展示边坡位移变形特征,同时可对边坡变形趋势进行预测,为边坡稳定性分析提供准确可靠的数据支撑。

Highway high slope generally has a high safety hazard and the instability will affect the safety of highway operation.By fully integrating new technologies such as Beidou satellite navigation and positioning,cloud computing and visualization,this paper constructs an automatic monitoring system of high slope based on GNSS to carry out real-time dynamic monitoring of slope displacement and deformation of a mountain highway,and at the same time uses servo total station to check and verify GNSS automatic monitoring results.It is found that GNSS automatic monitoring system of high slope has higher accuracy in planimetric displacement monitoring and slightly lower accuracy in vertical direction monitoring,but it can still meet the requirements of long-term monitoring of slope engineering.Compared with manual monitoring,GNSS automatic monitoring system of high slope can obtain real-time and all-weather slope displacement and deformation information,use high-frequency monitoring data to visually display slope displacement and deformation characteristics,and predict slope deformation trend,providing accurate and reliable data support for slope stability analysis.
