摘要
梨园水电站念生垦沟堆积体位于坝趾上游右岸念生垦沟内,约2000万m^3。受导流洞进口明渠开挖切脚及外部施工扰动影响,堆积体出现了变形滑动并逐步扩大,对工程产生的影响十分巨大。经过长达3年的Ⅰ-Ⅲ期综合治理,念生垦沟大型堆积滑坡体变形得到有效控制,并满足B类Ⅱ级水库边坡安全稳定要求。对念生垦沟大型堆积滑坡体治理思路、治理措施和治理效果进行了详细介绍,可供类似工程参考。
The Nianshengken accumulation body with a volume of 20 million m3 locates in Nianshengken Ravine upstream right bank of dam in Liyuan Hydropower Station. Influenced by the excavation of open channel of diversion tunnel and surrounding constructions, the accumulation body appears slide and the landslide gradually extended, which seriously affects the safety of project construction. After more than three years Phase I-III comprehensive treatments, the landslide deformation, of accumulation body has been effectively controlled, and meets the requirements of Class B(Ⅱ) reservoir on slope stability. The treatment ideas, measures and effectiveness of accumulation body are described in detail herein to provide references for similar projects.
