摘要

运用计算流体动力学技术对泥石流中的Bingham黏性泥石流流体对拦挡坝的冲击进行了数值模拟，所用软件为通用CFD软件CFX，使用CAD软件AutoCAD和Unigraphics（简称UG）建立了泥石流沟谷三维地形及拦挡坝模型，计算出泥石流的速度场及泥石流流体对拦挡坝的冲击力的大小与分布。

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.
