Study on the diffusion law of per meation grouting in oval fissure

Abstract：In order to study the diffusion law of grouts in fractured rock masses, the shape of single crack was simplified as oval in the model in the paper.Then, according to the generalized cylindrical coordinate, Newton law of inner friction, Darcy law, the seepage differential equations and the continuity equation under the boundary condition, the relationship of parameters in the progress of permeation grouting of Newton liquids in level oval fissure was deduced.Finally, the diffusion law of permeation grouting in oval cracks was studied.
