摘　　要：简要综述了国内外裂隙岩体单裂隙、水力耦合、非饱和及考虑填充物情况下的渗流特性物模试验研究成果,并做了相应的分析和讨论。分析表明:物模试验在研究裂隙岩体渗流特性方面具有不可替代的作用;需要进行更多的模拟实际岩体裂隙的试验;反映剪应力或三维应力影响的物模试验是一个需要加强的方向;真正意义上的非饱和渗流试验还很少;填充裂隙渗流的研究更具实际意义,也待于加强。分析结果为今后的裂隙岩体渗流特性物模试验研究提供了有益的方向。The researches on seepage characteristic of fractured rock masses under the conditions of single fracture, hydraulic coupling, unsaturated seepage and considering the filled materials are reviewed and analyzed relatively. The results show that the experimental study played a very important role in researching on seepage characteristic of fractured rock masses; the more experiments that can simulate exactly the actual rock fracture should be done; the experiments considering the shear stress and 3-dimensional stress should be emphasized; the fully reasonable experiments of unsaturated flow in fractured rock masses are few now; the research on seepage characteristic of the filled fractured rock masses is more significant and should be strengthened. The available research directions are put forward for the future research on seepage characteristic of fractured rock masses.
