杨家槽古滑坡，体积约８８０万ｍ３。在清江隔河岩水利枢纽兴建前夕，千余居民迁移到该滑坡体上居住。１９９１年地质初勘确认为基岩滑坡后，开展了滑坡内部和外部变形观测。稳定性监测以仪器监测为主，同时结合地质调查和宏观巡视检查。观测贯穿大堤蓄水前、蓄水期和运行初期全过程，取得了滑坡位移、降雨量、地下水、江水水位之间的相关关系。６年来的大量监测资料表明，杨家槽滑坡体在库水位下降时，滑舌部位仅出现微小向下位移，滑坡整体稳定性尚好，采取适当地表排水措施，可不予搬迁，但必须继续加强安全监测工作。
Yangjiagou ancient landslide, the volume of about 8.8 million m3. On the eve of the Qinghe Geheyan Water Control Project, more than a thousand residents migrated to the landslide to live on. After the initial geological survey in 1991 confirmed the bedrock landslide, the landslide internal and external deformation observation was carried out. Stability monitoring is mainly based on instrument monitoring, combined with geological survey and macro inspection inspections. Observe the whole process before, during and after storage of the dike, and obtain the correlation between landslide displacement, rainfall, groundwater and river water level. The monitoring data in the past six years show that when the reservoir water level of Yangjiacao landslide declines, there is only slight downward displacement of the sliding tongue, and the overall stability of the landslide is still good. Appropriate surface drainage measures can be adopted to eliminate the relocation. However, it is necessary to continue to enhance safety Monitoring work.
