摘　　要：为了解溪洛渡水电站左岸堆积体边坡的变形规律和保证边坡安全,在堆积体上布置了比较齐全的安全监测项目,包括内、外部变形,渗流和支护锚索荷载的监测。通过对长期观测资料的分析,揭示了边坡的变形规律与安全现状。结果表明:左岸堆积体边坡变形较治理前有收敛趋势;边坡排水系统的运行及锚索锚固的效果良好。但堆积体边坡未完全稳定,需加强监测以保证坡体及电站进水口的安全。In order to study the deformation laws of slope and ensure its safety,we set up relatively complete safety monitoring items on the accumulated body.Through analysis on long-term observation data,the deformation laws and status of the slope are revealed.The results show that,compared with that before treatment,the deformation of accumulated slope on left bank has a tendency of decreasing;the operation of drainage system of the slope and the anchoring effect are satisfying.However,the accumulated slope is not yet stable,monitoring needs to be strengthened so as to ensure the intake safety of Xiluodu Hydropower Station.
