摘要
水电站库区特大型滑坡的稳定性对于水电站坝工结构及周边人民生命财产安全具有重要影响,对该类滑坡稳定性及变形趋势进行大范围实时精确观测可为滑坡提供可靠的预警和治理信息,具有十分重要的意义。水电站库区滑坡传统监测方法主要以GNSS监测,全站仪监测等为主,本研究将国产先进的地基干涉合成孔径雷达系统LKR-05-KU-S100,应用于澜沧江大华桥水电站沧江桥—营盘滑坡和大华滑坡的监测。现场监测试验表明,该系统精度较高,可进行远距离、全天时、全天候、大范围监测,对于大型及特大型滑坡的监测具有独特的优势和广阔的应用前景。
The stability of large-scale landslide in the reservoir area of hydropower station has an important impact on the safety of dam structure and surrounding people’s life and property.Large-scale real-time accurate observation of the stability and deformation trend of this type of landslide can provide reliable early warning and control information for the landslide,which is of great significance.The traditional monitoring methods of landslide in the reservoir area of hydropower station are mainly GNSS monitoring and total station monitoring.In this study,the advanced GB-InSAR system LKR-05-KU-S100 is applied to the monitoring of Cangjiangqiao-Yingpan landslide and Dahua landslide of Dahuaqiao hydropower station on Lancang River.Field monitoring tests show that the system has high precision,and it can carry out long-distance,all-day,all-weather,and large-scale monitoring.It has unique advantages and broad application prospects for the monitoring of large and super-large landslides.
