In accordance with the Navier-Stokes equation between planar plates, the equation of motion of the Binghamian grouts is deduced in smooth and inclined fissures. The model indicates that the velocityof flow gradually reduce with the development of time. And the greater the pressure is, the greater the speed is, as a result, the Binghamian grouts has a further infiltration. The velocity of flow ofBinghamian grouts has nothing to do with fissure inclination. In addition, in the circumstance of the same parameters, the wider the fissure is, the slower the velocity of flow of Binghamian grouts is; thebigger the viscosity of grouts is, the slower the flow is; the smaller the initial shear strength is, the slower the flow is; the bigger the Binghamian grouts density is, the slower the flow is; and vice versa.
