岩体裂隙渗流水力特性的实验研究

Experimental research of hydraulic properties of seepage flow in fracture

根据数理统计原理，从随机平稳过程理论出发，提出了一套描述裂隙空间曲面几何形态的三维指标和方法。在一套特制的岩石裂隙渗流实验装置上系统地研究了不同几何形态的裂隙在不同应力、应变条件下的水力特性，探讨了渗透系数与机械隙宽、剪切变形、几何形态、应力条件、加卸载条件的关系，并得出了各种不同情况下的实验数据拟合方程式。

According to statistic stationary random process theory ,a set of three - dimensional indexes and methods describing the shape of spatial curved surface of rough fracture have been presented. Using the special experimental provision-of seepage flow in fracture,the hydraulic properties of natural rough fissures of different kinds of geometrical configuration have been studied under different stress and strain conditions. The research results show that the coefficient of percolation depends upon mechanic aperture, shearing deformation, fractured geometrical configuation,stress as well as loading and unloading conditions. A series of regular results and fitting equations of various conditions for test data are obtained.
