采用离散元方法,对5·12汶川地震诱发的牛圈沟滑坡动力过程进行数值模拟,通过与实际滑坡堆积形态和运动特点对比反演离散元模型参数,分析了不同基底摩擦系数时滑坡运动距离、堆积形态、内部颗粒运动规律以及运动过程的能量转换关系,有效地再现了地震诱发的滑坡动力过程,为西南地区潜在灾害预测与防治提供理论支持和技术指导.
Discrete element method is used to simulate the dynamic process of Niuqu’oung landslide induced by the 5.12 Wenchuan earthquake. The parameters of the discrete element model are compared with those of the real landslide by the comparison of the shape and movement of the actual landslide. The movement of landslide with different base friction coefficient , The accumulation pattern, the movement rules of internal particles and the energy conversion of the movement process, effectively reproducing the earthquake-induced dynamic process of landslide and providing theoretical support and technical guidance for the prediction and prevention of potential disasters in the southwestern area.
