摘　　要：三峡库区地质灾害监测预警工程是库区防灾减灾的重要手段。GPS监测作为高新技术在地质灾害专业监测中发挥了重要作用。文章介绍了三峡库区三级GPS监测网的构建,为全库区地质灾害监测预警提供了统一的坐标基准,为库区GPS基准网提供了准确的起算数据,为分析各滑坡体基准点的位移变形和稳定性提供了参考。实践表明,GPS监测技术能较好地满足三峡库区地质灾害监测预警的要求,能及时、准确地反映地质灾害体的地表变形情况及特征,为地质灾害防治提供科学的判断依据。Professional monitoring of geological hazards monitoring and forecast projects are important measures to prevent and forecast hazards in the Three Gorges Reservoir area. GPS monitoring as a new technique plays an important role in hazards monitoring. The united coordinate benchmark of geological hazard monitoring and forecast, accurate original data for GPS base web and stability of base points in every landslide are provided through the construction of three-grade GPS web in the TGR area. The practice of GPS deformation monitoring shows that the GPS monitoring technique is able to satisfy the needs of geological hazards monitoring and forecast projects, accurately reflect the deformation and its characteristics of landslide and provide scientific judge gist for the work of geological hazard monitoring and forecast.
