    Abstract

    Multiple sets of cracks exist in the fault fracture zone, damage zone and even intact rock mass, resulting in poor conductivity and high permeability of the hard rock fissure seepage channels. There are likely to become potential groundwater migration channels in the future, so that the underground engineering is facing huge challenges. To more accurately grasp the characteristics of the permeability of rock mass and fracture, it is extremely important to get hold of the phenomena of internal structure model, genetic mechanism and dynamics principle in the multiple scales size and depth of rock fracture. In assurance of an accurate analysis result in the multiple scales of rock mass fracture, mastering the principles and patterns of the solute and flow medium migration rule in pore and fracture can provide scientific basis for underground construction engineering.
