岩体结构面渗流研究现状

Present research state for permeability of jointed rock mass

岩体渗流实质上就是结构面及其网络的渗流 .由于受节理张开度、表面粗糙度、接触面积、裂隙法向应力变化和填充物等影响 ,从而使岩体结构面的渗流特征变得非常复杂 .

The permeability of characterization of jointed rock mass is mainly depended on the geometric characterization of fissure space. For the influence of variable joint aperature, surface roughness, contact area, variable normal stress level and infilling material, it gets very complicated. In this paper, the present research state for permeability of jointed rock mass is detailed on both aspects of numerical and empirical analogy for geometric characterization of rock joint. \;
