本文根据岩石节理非饱和渗流试验所测定的节理排泄和吸湿过程，探讨了节理非饱和渗流机理，提出了基于节理概率分布的毛细压力与饱和度的解析模型以及节理非饱和水力传导度的理论表达式．研究表明，单节理非饱和渗流特性与二维非均质多孔介质具有一定的相似性，本文提出的有关模型可作为确定岩石节理非饱和渗流参数的基本方法．
In this paper, according to the joint discharge and moisture absorption measured by the unsaturated seepage test in rock joints, the unsaturated seepage mechanism of jointed joints is discussed, and the analytical model of capillary pressure and saturation based on joint probability distribution and the theoretical expression of joint unsaturated hydraulic conductivity formula. The results show that the single-joint unsaturated seepage characteristics have some similarities with the two-dimensional heterogeneous porous media. The relevant model proposed in this paper can be used as the basic method to determine the unsaturated seepage parameters of rock joints.
