摘要: 付家岩滑坡是三峡库区地质灾害专业监测预警工程二期专业监测点,监测方法有地表位移监测和钻孔深部位移监测。通过对3年的监测资料进行对比分析,结果表明各GPS变形监测点在水平向和垂向均有明显变形,其中纵Ⅱ、纵Ⅲ剖面GPS监测点变形尤为突出;各钻孔监测点变形明显,监测主纵剖面中下部钻孔变形突出。目前滑坡处于匀速变形阶段,为不稳定状态。Abstract: The Fujiayan landslide is a professional inspecting spot for the second early warning project of geological hazards inspecting in the Three Gorges Reservoir area. The inspecting method is surface displacement monitoring and deep displacement monitoring of the landslide body. Based on the contrast analysis of monitoring data over 3 years, it is found that there is some horizontal and vertical directions of deformation in each GPS deformation inspecting point, and the deformation in the monitoring point on the No. Ⅱ and No. Ⅲ sections is quite obvious. Each borehole have a obvious deformation, and the hole on the middle and underside cutaway section has a sharp deformation. At present the landslide is at a deformation stage of a uniform speed and at a unstable state.
