摘要：

Soil slope failure is characterized by large deformation, which cannot be modeled by finite element method (FEM) because of excess meshes distortion. To overcome this limitation, general particle dynamics (GPD) code (GPD3D) is developed to analyze the stability of soil slope. The Drucker-Prager yield criterion is implemented into the GPD code (GPD3D) to describe the deformation behaviors of soil slope. Then, the failure of soil slope is analyzed to illustrate the performance of the proposed method. Numerical results by GPD3D are then compared with the solutions by FEM. It is indicated that the proposed GPD code can be well applied in large deformation and failure of geomaterials. © 2019 John Wiley & Sons, Ltd.
