Study on Irregular Geometric Hydraulics Property of Rock Mass Fracture

The seepage of irregular fracture is a very important problem in rock hydraulics. On the basis of the experiment of a single fracture seepage,this paper proposed that the out of plane tortuosity be simulated by a sinusoidal seepage model and the in plane tortuosity by the seepage model of “carpet” cones. The statistical analysis of results of the experiment shows that the irregular fracture seepage has fractal effects.
