摘　　要：三峡库区地质环境脆弱,是我国滑坡灾害的多发地区,因此,有效开展滑坡监测已经成为三峡库区地质灾害防治的一项重要任务。目前,三峡库区的滑坡监测系统已初步得到建立,大量新技术和新方法的应用成果,为及时准确掌握三峡库区滑坡的变形状况、预测预报滑坡的发生提供了科学依据。文中着重介绍了GPS大地形变测量、自动伸缩计地表位移测量、合成孔径雷达干涉测量、TDR滑坡体深部变形测量和自动远程遥控监测等新技术和新方法的应用情况,并对各自的优缺点进行了分析和比较。指出在三峡库区滑坡监测中,应该根据滑坡自身特点、监测目的和仪器的特性,合理选择监测方法。Three Gorges reservoir is a region where high incidence of the landslide disaster and the geological environment is fragile. So, it is highly important duty that we keep the landslide monitoring effectively to the geological disaster prevention of the three gorges reservoir. At the present time, landslide monitoring system of three gorges reservoir has been preliminarily established, a large number of application achievement of new technology and method supply scientific evidence for mastering the landslide deformation status of three gorges reservoir accurately and forecasting the landslide occurrence. This paper mainly introduces the new technology and method application status of GPS measurement,extensometer measurement,Interferometry Synthetic Aperture Radar,TDR landslide deep deformation measurement and automatic remote measurement, the merits and faults are also been analyzed and compared. The results show that monitoring method should been properly selected according to landslide characteristic, monitoring purpose and equipment character on landslide monitoring in three gorges reservoir.
