钻孔倾斜仪监测在塘角村1^#滑坡预警监测中的作用

塘角村1^#滑坡是三峡库区地质灾害防治监测预警工程Ⅲ期专业监测点。监测方法为滑体深部位移监测、地表位移监测,同时开展地表宏观变形调查。2007年4月滑坡开始出现变形;其中滑体深部位移由钻孔倾斜仪监测,最早发现滑体变形,随后地表位移GPS监测滑体出现变形,同时滑体地表出现裂缝,滑体局部产生溜滑现象;文章通过滑体深部位移实测监测数据纵向分析,结合与其它监测方法（GPS）监测数据进行横向对比分析印证,判断钻孔倾斜仪监测数据的有效性、准确性;阐述钻孔倾斜仪监测在塘角村1号滑坡预警监测中的重要作用。

The effect of inclinometers for slope monitoring of No.1 Landslide in Tangjiao Village

No. 1 landslide of Tangjiao Village is the third professional monitoring site for the monitoring and pre-waming project of geological disasters＇ in the three gorges reservoir region. Monitoring methods include deep displacement monitoring, surface displacement of the landside bed. At the same time, macroscopical deformation investigation was developed. On April of 2007, the landslide appeared deformation, which was monitored by deep displacement firstly, and then surface displacement showed the landslide deformation. The landslide bed appeared crack and slides. In this paper, according to the lengthways result of landslide deep displacement data, combining with the GPS data analyse, the authors confirmed that the monitoring data by Inclinometers was reliable and exact. Furthermore＇ we considered that it is important to apply the inclinometers to No. 1 landslide of Tangjiao Village.
