摘要
水电站库区是地质灾害的多发区和重灾区,快速、精准地识别地质灾害隐患点是水电站安全管理的难题之一。机载激光雷达可快速获取高精度的地理信息数据,为地质灾害信息可视化解译提供重要技术手段。通过获取福堂坝水电站的点云、影像数据,得到DEM和DOM成果,解译滑坡、泥石流、崩塌为主的地质灾害,共解译出地质灾害隐患点共6处,包含滑坡2处、泥石流2处及崩塌2处,为库区地质灾害的管理与防治提供科学决策依据。
The reservoir area of the hydropower station is a geological disaster-prone and hardest-hit area.Rapid and accurate identification of geological disaster potential points is one of the difficulties of hydropower station safety management.Airborne lidar can quickly acquire high-precision geographic information data and provide important technical means for the visual interpretation of geological hazard information.By obtaining the point cloud and image data of Futang Dam Hydropower Station,the results of DEM and DOM are obtained,and the geological disasters dominated by landslides,debris flows and collapses are interpreted,and 6 hidden points of geological disasters are interpreted,including 2 landslides,2 debris flows and 2 collapses,which provides a scientific decision-making basis for the management and prevention of geological disasters in the reservoir area.
