梨园水电站念生垦沟堆积体安全监测分析

Safety monitoring and analysis on Nianshengkenengou accumulation body at Liyuan Hydropower Station

念生垦沟堆积体位于金沙江梨园水电站导流洞进口边坡右侧的坝前右岸宽缓沟谷中,其稳定与否对梨园水电站的建设至关重要,并关系到电站建设的成败。为了保持念生垦沟堆积体的稳定,在堆积体不同高程处采取了抗滑桩、锚索加固等措施,并布置了钢筋计、测缝计、锚索测力计、测斜仪、水位计等安全监测仪器。监测数据准确反映了念生垦沟堆积体在不同工况下的安全状态,为保障安全施工发挥了积极作用。

Nianshengkengou accumulation body is located at right side of diversion tunnel entrance of Liyuan hydropower station on Jinsha River,its stability is very important to the power station construction.In order to ensure the stability of the accumulation body,the reinforcement measures of anti-slide pile,anchor cable were adopted at different elevations of the accumulation body and surface monitoring points as well as deformation safety monitoring devices of steel bar meter,joint meter,anchor dynamometer,inclinometer,water level gauge etc were arranged.The monitoring data accurately reflected the safety state of the accumulation body under different working conditions and were beneficial in guaranteeing construction safety.
