Abstract: This paper inqures into the energy equation of debis flow in drainage canal, according to the law of coservation of energy.Mean current velocity of any transverse section of the debris flow of the aqueduct can be ascertained from this equation.and this paper also gives the course of inference of the equation,the formula of hydraulic raidius and energy loss of the debris flow in the process of flowing.Meanwhile this paper makes concrete analysis of all parameters? 玜\-1、a\-2、a\-3、ξ\-1、ξ\-2、n\-1、n\-2 ,especially first leades into a revised coefficient K contrast debris flow with water.Finally the theory is applied to the design of aqueduct of debris flow in pinchuan.K value( K =1 3) is obtained by a model experiment, and it is revised to 1 4 by inspection of the scene, then utilizing the equation,mean current velocity of the debis flow is reached in the exit transverse section of the equeduct.

Key words: debris flow, drainage canal, current velocity
