摘　　要：研究区岩体节理裂隙发育,岩土结构复杂多变;滑坡区滑体厚度变化大,滑带埋深较大。滑坡受到地质构造作用、地下水水位变化、人类工程活动等因素影响,加剧了滑坡区变形,致使形成了大型深层岩质滑坡。文章以滑坡工程实例为基础,从地形地貌学、工程地质学、构造地质学等知识层面,分析了滑坡变形特征及影响因素,为滑坡灾害的防灾抢险提供了一定的理论基础。The rock mass joints and fissures in the study area are developed,and the rock and soil structure is complex and changeable.The thickness of the sliding body varies greatly in the landslide area,and the depth of the sliding zone is large.Landslide is affected by geological structure,groundwater level changes,human engineering activities and other factors,which aggravate the deformation of landslide area,resulting in the formation of large deep rock landslide.Based on the landslide engineering example,this paper analyzes the main influencing factors of landslide deformation from the knowledge theories of topography and geomorphology,engineering geology,structural geology and so on,which provides a certain theoretical basis for the prevention of landslide disasters.
