摘要
The simulation model is based on fluid mechanics and soil mechanics.Differential equations reflecting landslide movement are converted into algebraic equations by the differential method and calculation program is prepared.The three-dimensional simulation of the Sanyuandong Landslide shows that it will have a long sliding distance,a big scope and thick accumulation,with huge risk.It turns out that the model has good applicability for the simulation of loess landslide movement.
