通过对工程区区域地质环境、滑坡所在山体基本地质条件研究，分析了该滑坡的成因机制，认为滑坡体的形成历史与河流的发育过程紧密联系及特殊的岩性组合造就了该区特殊的河谷形态，并提供了广阔的第四系物质赋存空间，并进而演化形成了现有的崩塌体空间形态和变形表象；在深入分析该滑坡基本特征的基础上，以地形地貌、变形迹象及物质组成差异性为依据，对该滑坡变形机理进行论述，重点评价影响堆积体稳定性的诱发因素，结果表明，堆积体滑坡的变形机制是受粘土层的控制，堆积体在地下水的长期作用下产生蠕滑—拉裂变形，并具有牵引式破坏的典型特征，最后提出了相应的工程措施。

Due to the study of the project area regional environmental geology, basic geological conditions of the mountain accumulation body, the genetic mechanism of the accumulation of body was analyzed. It is thought that the closely connection between the history of formation of the landslide dam and the development process of river, and the special litho logy combination created the special form of river valley, provide a broad space for quaternary matter occurrence, and formed the existing body space form the collapse and deformation. Based on the analysis of the basic characteristics of the pile, taking topography, deformation signs of damage and material composition of differences as the basis, the deformation mechanism of landslides was discussed, the induced factors of the deposit stability are mainly accumulated. The results show that the deformation mechanism of landslide deposit is controlled by clay layer, the deposit crept and ripped by the long-term effects of underground water, it has the typical characteristics of pull-type destruction. Finally, the corresponding engineering measures are put forward.
