| Abstract: | The Computational Fluid Dynamics (CFD) technology [1] is used to numerically simulate the Bingham viscous debris flow which is a kind of debris flow. The software used in this study is CFX which belongs to the current CFD software, the 3D landform of debris flow cleuch and blocking dam model is created by the CAD software of Unigraphics (UG) and AutoCAD, the velocity field of debris flow and dimension and distribution of debris flow fluid pressure on blocking dam are calculated by the computation. |
