摘要
以隙宽均一单裂隙水流的立方定律及流体力学的基本方程为基础，对隙宽不均一单裂隙渗流模型进行了分析，得出了隙宽不均一单裂隙渗流量等效的等效隙宽公路；并将此公式应用于岩体裂隙网络渗透模型分析中，检验了等效隙宽公式的有效性。
Based on the cubic law of flow in single fissure with unmiform openings and the fundamental equations of fluid mechanics,the seepage model of single fissure with variable openings is analyzed,the formula of the equivalent aperture of fractures with vdriabe openings is deduced by means of the principle of the same flow rate.The formula is applied to analyze the fluid flow model through fracture network with variable aperture of rock mass,which verifies the effectiveness of the formula
