研究岩块相对不透水情况下大尺度裂隙中渗流运动的规律及其计算。推导了各种不同流态时计算渗流的公式，阐述了裂隙开度和应力的关系，介绍了考虑应力影响时的计算方法。算例表明了应力状态对渗流计算的显著影响。
Study on the Law and Calculation of Seepage Flow in Large Scale Fractures Under the Condition of Relative Permeability of Rock Mass. The formulas for calculating seepage flow in different flow regimes are deduced. The relationship between fracture opening and stress is expounded. The calculation method for considering the effect of stress is introduced. The example shows the significant influence of stress state on seepage calculation.
