| Abstract | Smoothed particle hydrodynamics (SPH) is now becoming more and more welcome in modeling large defor-mation, soil failure and landslide in geotechnical and geological community. Aiming to solve the low efficiency problem in modeling large-scale long run-out landslide, this study implemented a GPU-accelerated SPH model based on the Drucker-Prager yield criterion with a non-associated flow rule on the open source platform DualSPHysics (v4.0). Two typical three-dimensional (3D) cases with simple boundary conditions were simulated to validate and demonstrate the high effectiveness and capacity of the GPU based elasto-plastic SPH model in modelling large deformation, failure, runout and deposit in a unified framework. Furthermore, we used the GPU-based elasto-plastic SPH model to simulate the Yigong avalanche and Shenzhen landslide to reproduce complete landslide dynamic processes and deposit detail, where a comparable deposit distribution with field survey was found. It is concluded that the implemented GPU-based elasto-plastic SPH model is able to simulate large scale long runout landslides on complex terrain to provide full process and deposit, which could be helpful for hazard assessment and mitigation. |
