摘要
以二维立面纳维尔－斯托克斯（Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ）方程为基本方程，将沟道泥石流视作为一种宾汉体．对三种不同纵坡情况下的沟道泥石流流场进行了数值模拟，并与相应的野外实验进行了对比，取得了较好的结果．
Numerical simulations of gully debris flow are presented. The Navier-Stokes equation and continuity equation were solved. Based on Bingham model. 3 velocity profiles were given,correspodins 3 different conditions of bottom slope in flow field were compared with the same test in the field.
