中文摘要：

滑坡的失稳破坏是一个岩土体的滑动、平移的复杂过程。本文根据黄河库岸滑坡的工程地质条件,建立滑坡体的颗粒流数值模型,运用二维颗粒流程序（PFC2D）分析了该滑坡体的复杂破坏特征。结果发现,该滑坡的变形破坏是一个时间过程。利用颗粒流软件可以从微观角度再现该滑坡发生、发展以及最终趋稳的全过程,为处于不同变形破坏阶段的滑坡治理提供依据。

英文摘要：

The unstable failure of landslide is a complex process that exists in the sliding and translation of the rock and soil body. Based on the engineering geological conditions of landslide on reservoir Bank of the Yellow River, this paper establishes the particle flow numerical model of landslide. Using the two-dimensional particle flow code （PFC2D）, characteristics of complicated destruction of the landslide are analyzed. It is con- cluded that the landslide deformation failure is a time process, using particle flow software can realize the land- slide occurrence, development and stabilization of the whole process of the final. The conclusion provides the basis for in various stages of deformation and failure of landslide control.
