黎家洞滑坡变形机制研究

通常认为顺层岩质斜坡的变形破坏以滑移-拉裂、滑移-弯曲模式为特征,但野外调查中,在陡倾顺层岩质边坡还发现一类特殊的变形破坏方式,即倾倒变形。以黎家洞滑坡为例,在阐明区内地质环境条件、滑坡的基本特征的基础上,应用数值模拟手段对该滑坡的倾倒变形机制进行了分析。研究成果为该类滑坡除险加固提供了参考依据。

STUDY ON FORMATION MECHANISM OF LEIJIADONG LANDSLIDE

Generally speaking,it is believed that slip-rupture and slip-bending are main characteristics of deformation and fail-ure of bedding rock slope.However,it is found that there is another particular form of deform-ation and failure for steep bed-ding rock slope on situ survey,namely,toppling deformation.Taking Leij iadong Landslide for an example,on the basis of clarif-ying geological environment conditions in the region and basic characteristics factors of the landslide,the toppling deformation mechanism of the Landslide is been carried out mainly by numerical simulation.This study serves as a reference for the rein-forcement of the Landslides.
