摘要
长江三峡库区岸坡有 1 3 4处大型的崩塌滑坡堆积体 ,其成因与长江三峡干流的深切作用有关 ,陡直岸坡部分发生张裂 ,随后有裂块的崩滑。崩塌滑坡运动是能量的释放 ,并趋于稳定。建库后 ,最危险的是蠕动中的裂块 ,要注重部分滑移面的固结 ,其次是清理库水位高程岸坡上的不稳定物质。
There are 134 large-scale accumulations of the collapsed ladnslide along the bank slope of the Three-Gorge reservoir.Their formation related to the depp-dissection of the mainstream of the Changjiang River in the Three-Gorge area.The steep bank-slopes cracked and the fissured rocks collapsed.The collapsing and landslide lead to power release and make the bank-slope tend to be stable.After the Three-Gorge reservoir will have completed,the vermicular fissure rocks would be most dangerous.So we should pay attention to the concretion of some slippage-surface and clear up unstable rocks on the bank-slope.
