摘　　要：根据水量守恒原理和任何闭合环路上的水头损失之和等于零的原则，建立了二维裂隙网络渗流模型，并引用连续介质有自由面渗流初流量法基本原理，求解有自由面裂隙网络渗流问题。其次，初步分析了裂隙方向和裂隙密度以及排水点的存在对裂隙网络渗流场的影响。Based on water conservation theorems and principle that sum of head losses in any closed loop e-quals zero,model for two-dimensional fissure network seepage is established.Problem of fissure network seepage is established,’Problem of fissure network seepoge with free face is solved by primary flow method for seepage with continous midium and free face. Besides,influence of fissures orientation,closeness and existence of drainage points on fissure network seepage field is primarily studied.
