摘　　要：通过解析法和数值方法对层状裂隙的渗透等效性进行了研究,分析了两种方法对等效性计算结果的差异,得到不同分析方法的适用条件;分析了层状裂隙岩体中不同种类裂隙隙宽的变化对等效渗透性的影响,得到了层状裂隙岩体等效渗透性的一般规律。The article is based on study penetrability equivalent of stratum cracks by the resolution and value methods and analyzes differences of two calculated results. It gets the suitable condition by the different method. It analyzes gap space changes among all different kinds of cracks in the stratum rock to be a influence on equivalent penetrability and gets its general regulation.
