纳雍骔岭片区高位崩塌(危岩)带形成机制研究

Researching Formation Mechanism of The Slide(Crag)Area of Zongling in Nayong County

纳雍骔岭片区高位崩塌(危岩)带形成机制主要表现为陡崖岩体受特殊的地形地貌、软硬相间的岩性组合关系以及陡倾的构造节理切割等内部因素的控制,造成岩体破碎,稳定性差,在强降雨、冻融作用、采矿工程活动等外部因素的共同影响作用下,诱发陡崖地段危岩体的变形失稳而形成崩塌地质灾害。

The slide(crag)area of Zongling in Nayong county is affected special topography and geomor-phology,lithology combination relationship between soft and hard faces,steep dip structural joints and so on,what is caused of fractured rock mass,on this basis,suffered human engineering activities,rainfall,snow and so forth,induced the large of block crag,happened the slide geologic hazard.
