利用不溶混驱替的方法，在室内精确地观测了花岗岩节理非饱和渗透排泄和吸湿过程，探讨了节理非饱和渗透机理，提出了基于节理张开度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，单节理非饱和渗透特性与二维非均质多孔介质具有一定的相似性，文中提出的有关模型可作为确定岩石节理非饱和渗透参数的参考方法。
Using the method of immiscible flooding, the non-saturated infiltration and absorption processes of granite joints were observed indoors. The mechanism of unsaturated infiltration of joints was discussed. An analytical model of capillary pressure and saturation based on the distribution of joint opening degree was proposed. Theoretical Expression of Unsaturated Hydraulic Conductivity. The results show that the single-jointed unsaturated seepage characteristics have some similarities with two-dimensional heterogeneous porous media, and the relevant models proposed in this paper can be used as a reference method for determining unsaturated seepage parameters of rock joints.
