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。
The Tomb Ping landslide body is one of the major landslides in the Geheyan reservoir bank of the Qingjiang River. There have been many landslides in history. In order to monitor the stability of the landslide body before and after the impoundment of the reservoir, on-the-spot measurements were carried out by laying borehole inclinometers on the landslide body and laying out monitoring points for external deformation monitoring. The monitoring results show that the induced earthquake in the early stage of reservoir impounding resulted in the violent deformation of the XujiaTai secondary landslide body (tomb), which had an adverse effect on the overall stability of the landslide body.
