Study on numerical simulation of impact factor on debris flow to bauxite tailings dam

摘要

The geological disaster in Guizhou is serious, especially the debris flow, brings many hidden dangers to the mine construction. In this study, we set up the three dimensional numerical model of dam break, changing the viscosity coefficient, yield stress and height of dam break to study the impact of every factor on debris flow. Set different forms of landslide and diversion dam, studied the impact of dam on characteristics of debris flow, and obtained the optimal location and angel of landslide and diversion dam.
