英文摘要	Vast expanse of land in the northwest China is covered by thick loess. In recent years, due to the transformation of mud flow channel and the change of environment, mud flow disaster is rising in loess areas. The movement characteristics of mud flow were studied on the basis of the model of mud flow ditch and orthogonal experiment. The results show that discharge has the largest impact on mean velocity, flowed by unit weight and ditch slope angle. The instantaneous velocity is wavy with time. The alternating change between peaks and valleys shows that bedding layer and valley shape have a great influence on mud flow movement. When the unit weight is constant, the bigger the flow rate is, the bigger range of the instantaneous velocity will be. Intermittent debris flow is very obvious during mud flow moving, and the more the discharge is, the more the intermittent debris flow will be. The intermittent debris flow chart can provide a reference for early warning and prevention of mud flow. ©, 2015, China Water Power Press. All right reserved.
