长江三峡链子崖危岩体和黄腊石滑坡防治工程

The Control Works of Lianziya Dangerous Rock Mass and Huanglashi Landslide in the Three Gorges of Yangtze river

本文重点论述了三峡库区危险性和危害性最大的链子崖危岩体与黄腊石滑坡的地质特征及其防治工程。针对它们的形成机制与诱发因素， 链子崖危岩体的防治， 主要采取底部煤层采空区的承重阻滑工程与其上危岩体的预应力锚固工程； 黄腊石滑坡的防治， 主要采取地表与地下排水工程。目前， 两处工程均已基本完成， 效益明显。

Lianziya dangerous rock mass and Huanglashi landslide are the two most dangerous geo hazards in the Three Gorges area of Yangtze river, the comprehensive measurements to control the geo hazards have been taken according to the triggering factors and the formation mechanism of these geo hazards The Lianziya dangerous rock mass was formed under the influence of cliff gravity, working out bottom, karstification and rock weathering with the favorable structure, well developed fissures and small faults The major controlling engineering for the Lianziya dangerous rock mass is pre sttessed anchoring and the slide resistant bonding underlying The Huanglashi landslide is located on the north bank of the Yangtze River, 1 5km east to Badong County The rainfall is the main triggered factor of landslide So, the principle measurements of prevention are ground water drainage and surface water draingage Now the main control works have been finished and have remarkable effect on control of the two hazards
