摘要
文中系统推导了裂隙网络模型,正交和非正交裂隙组的连续均质场模型计算公式,编制了数值计算方法的程序并应用于实例,还用物理模型加以验证。 经过多次裂隙渗流与多孔介质渗流计算比较,裂隙渗流的自由面显著高于多孔介质,因此研究裂隙岩体渗流和岩坡的稳定性以采用裂隙渗流计算方法为可靠。
In this paper, the computational formulas of fractured networks model and continuously homogeneous field models of fractures intersected either orthogonally or non-orthogonlly are derived systematically. The program for numerical analysis methods is compiled and has been applied to practical examples and checked by physical models.
After numerous computations for comparison with seepage flow in fractures and in porous media, the phreatic surface is much higher in fractures than that in porous medium. Consequently, in the study of seepage flow in fractured rock masses and the stability of rock slope, the formulas of fracture seepage should be adopted and it is believed more reliable.
