摘　　要：墓坪滑坡体是清江隔河岩水库库岸大型滑坡体之一，历史上曾多次发生过滑坡。为了监测水库蓄水前后该滑坡体的稳定性状态，通过在滑坡体上埋设钻孔倾斜仪和布设外部变形监测网点等监测手段来进行现场现测。监测成果表明：水库蓄水初期诱发地震导致了（墓坪）徐家台次级滑坡体的剧烈变形，对滑坡体整体稳定性产生了不良影响。As one of the large scale landslides in the Qingjiang reservoir bank area, the Muping landslide body slipped several times in history. Field observation methods, including inclinometers and surface deformation monitoring networks, have been used to monitor the stability of the landslide before and after inpoundment of the reservoir. Monitoring results indicate that the earthquake induced by impoundment in the initial stage resulted in the acute deformation of Xujiatai sub-landslide of the Muping landslide, which affected the stability of the landslide body.
