摘　　要：从滑坡的环境条件、形态特征与变形特征入手,对滑坡成因机制、稳定性进行分析研究。滑坡区后期建房切坡及农田改造形成的多级陡坎,为变形提供了良好的临空条件,在降雨入渗及重力作用下,变形逐步加剧,并最终导致滑坡复活。通过滑坡稳定性定性与定量评价认为,滑坡目前处于缓慢加速变形阶段,一旦条件成熟,可能发生整体破坏。针对滑坡稳定现状,提出了有针对性的防治措施建议。Start with the environmental conditions of the landslide,morphological characteristics and deformation characteristics,the paper studies genetic mechanism and stability of landslide.Under the action of rainfall infiltration and gravity,deformation becomes even worse and eventually lead to the resurrection of the landslide.Qualitative and quantitative evaluation of landslide stability indicates landslides are in slow speed deformation stage,once the conditions are ripe,the overall damage may occur.In view of status of landslide stability,the paper proposes pertinent prevention measures.
