摘　　要：滑坡的形成原因很多,降雨、人工切坡、地震均使稳定坡体诱发滑坡。新的滑坡其滑坡原因通过现场调绘容易得知,但是对于百年以上老滑坡由于多年的风化、人为扰动、雨水冲刷及裂缝自然充填,滑坡原因被掩盖。文章在调绘的基础上对洩山老滑坡的形成原因进行了分析,旨在为同类滑坡的形成提供参考,为老滑坡的防治提供依据。There are many reasons for the formation of landslides,such as rainfall,artificial slope cutting,and earthquakes,which can all induce landslides on stable slopes.The cause of a new landslide can be easily determined through on-site mapping,but for an old landslide that is over a hundred years old,the cause is obscured due to years of weathering,human disturbance,rainwater erosion,and natural filling of cracks.On the basis of annotation,the article analyzes the causes of the formation of the old landslide in Xieshan,aiming to provide reference for the formation of similar landslides and provide a basis for the prevention and control of old landslides.
