江坪河水电站梅家台滑坡体安全监测与资料分析

江坪河水电站下游梅家台滑坡体经过综合治理后,设置了安全监测项目评价治理效果和滑坡体的稳定性。监测成果显示,梅家台滑坡体内部变形主要为蠕变,未发现明显的错动滑动现象,变形趋于收敛;地下水位变化平稳;钢筋桩、锚杆、预应力锚索等支护结构受力不大,应力变化稳定。梅家台滑坡体通过综合治理取得了良好的效果,滑坡体处于较为稳定的状态。

Safety Monitoring and Data Analysis of Meijiatai Landslide at Jiangpinghe Hydropower Station

After the comprehensive treatment of Meijiatai Landslide at the downstream of Jiangpinghe Hydropower Station, the safety monitoring system is set up to evaluate the treatment effect and the stability of landslide. The monitoring results show that,( a) the internal deformation of Meijiatai Landslide is mainly creep, there is no obvious slip, and the deformation tends to convergence;( b) the groundwater level is stable;and( c) the supporting structures including steel piles, anchor bolts and prestressed anchor cables are under low load, and the stress is stable. It shows that the comprehensive treatment of Meijiatai Landslide has achieved good results, and the landslide is in a relatively stable state.
