摘    要:金安桥水电站边坡安全监测表明:左岸B20崩塌堆积体边坡的稳定性受下部挡墙基坑开挖切脚及汛期降雨影响十分敏感,分析了堆积体边坡的变形特征和失稳机理。左右岸其它部位边坡经过2004年~2006年两年多的安全监测和汛期考验,边坡总体运行正常。监测投入了大量先进的仪器设备,取得了较丰富的现场监测资料,并及时整理分析反馈应用到工程中,为边坡安全预警、工程处理决策和安全施工起到了重要的指导作用,可供类似工程参考。

关 键 词:崩塌堆积体  变形特征  破坏机理  边坡安全监测与预警  金安桥水电站

Abstract:Through the slope safely monitoring in Jin'anqiao Hydropower Station,it is shown that the influence upon the stability of slope of B20 collapse accumulation from the excavation shear pin of the lower retaining wall and the rainfall in flood period is very sensitive,and the deformation characteristics and instability mechanism of slope of the accumulation are analyzed.The other slope of left and right bank are in normal operation through more than two years of the safety monitoring and tests in flood period ...
Keywords:collapse accumulation  deformation characteristics  failure mechanism  slope safety monitoring and early warning  Jin'anqiao Hydropower Station
