Non-Dorcian seepage equilibrium analysis of splitting grouting fluid in smooth single fracture

In this paper, the slurry seepage dynamics model is established, the critical conditions for instability of the seepage dynamics model are discussed, and the effects of power index, effective mobility and non-Darcian flow factors on the seepage velocity are analyzed. The results show that in the two-dimensional logarithmic parameter space, the boundary between the stability zone and the instability zone of seepage is a straight line, and the absolute value of the slope of the straight line decreases with the increase of the power index.
