在相同地质环境条件下沟谷两岸发生相向滑动的滑坡,可称之为“对滑”型滑坡。以陕西子长县阎家沟滑坡为例,讨论了“对滑”型滑坡的形成环境、发育模式、成因机制和后期变形演化特征。在此基础上提出了陕北大量发育的“对滑”型滑坡的整治措施。 Under the same geological conditions, landslides that occur on opposite sides of the valley can be called “slippery” landslides. Taking Yanjagou Landslide in Zichang County, Shaanxi Province as an example, the forming environment, developmental mode, genesis mechanism and evolution characteristics of later landslide are discussed. On this basis, a large number of “slippery” landslide remediation measures are put forward in northern Shaanxi.
