摘　　要：研究区受构造、裂隙和层面作用,岩体节理裂隙发育,岩层倾向受陡倾裂隙控制与岩层面相交切割形成顺向滑移的空间组合。滑坡受到地质构造作用、人类工程活动等因素影响,加剧了滑坡区变形,致使滑坡沿软弱面发生滑移-拉裂破坏。文章以滑坡工程实例为基础,从地形地貌学、工程地质学、构造地质学等知识理论,分析滑坡变形特征及破坏机理,为滑坡灾害的防灾减灾提供一定的理论基础。The study area is affected by structure,fissures and bedding planes.the joints and fissures of rock mass are developed.the rock strata tend to be controlled by steep fissures and intersect and cut with the bedding planes to form a spatial combination of forward sliding.Landslide is affected by geological structure and human engineering activities,etc.,which intensifies the deformation of landslide area and leads to slip-pull failure of landslide along soft surface.Based on landslide engineering examples,this paper analyzes the deformation characteristics and failure mechanism of landslide from the knowledge theories of topography and geomorphology,engineering geology,structural geology,etc.,which provides a certain theoretical basis for the prevention of landslide disasters.
