：斜坡变形乃至破坏是一个动态的地质力学过程，这个过程是应力～位移关系控制的大变形过程和由应力与应变状态控制的小变形过程。宝塔滑坡除具有不变形特征外，还兼有弹性、弹塑性和流变性等小变形特征。本文通过建立宝塔滑坡复活变形机制的“概念模型”，运用可变形块体离散单元法进行数值模拟，通过对模型的时间延拓，获得对地质体演化的认识，达到预测和防治方案优化的目的。
: Deformation or even failure of slope is a dynamic geomechanical process. This process is a large deformation process controlled by stress-displacement relationship and a small deformation process controlled by stress and strain conditions. Apart from the non-deformable features, the pagoda landslide combines small deformation features such as elasticity, elasto-plasticity and rheology. In this paper, a “conceptual model” of the resurrection deformation mechanism of the Baota landslide is established, and the numerical simulation is carried out by using the deformable block discrete element method. The time extension of the model is used to obtain the understanding of the evolution of the geological body and achieve the purpose of forecasting and prevention and control programs .
