为明确单裂隙饱和—非饱和渗流的基本规律对整个裂隙岩体渗流的作用，利用自行设计制作的单裂隙渗流实验装置，进行了不同隙宽、不同饱和水位、不同降雨强度下的一系列渗流实验，建立了裂隙隙宽与负压、饱和度与负压、裂隙隙宽与饱和度以及负压与非饱和渗透系数之间的实验关系，给出了各参数间的非线性函数式，这些关系式的确立丰富了裂隙渗流理论，为探明实际工程中裂隙岩体非饱和区的渗透荷载分布特征提供了新的有效方法。
In order to clarify the effect of the basic law of single-fracture saturated-unsaturated seepage on the seepage of the entire fractured rock mass, a series of seepage flows with different gap widths, different saturated water levels and different rainfall intensities were carried out by using a single fracture seepage experimental device designed by itself. Experiments were carried out to establish the experimental relationship between crack width and negative pressure, saturation and negative pressure, crack width and saturation, as well as the negative pressure and unsaturated permeability coefficient. The nonlinear function formulas were established for each parameter The establishment of the relations enriches the theory of seepage of fractures and provides a new effective method to find out the distribution characteristics of seepage loads in the unsaturated zone of fractured rock mass in practical engineering.
