摘　　要：不规则裂隙的渗流问题是岩体水力学中一个比较复杂的问题。本文通过单裂隙渗流规律的模拟试验，提出了用正弦渗流模型模拟面外曲度渗流，用“地毯”状锥体渗流模型模拟面内曲度渗流。试验结果的统计分析表明。The seepage of irregular fracture is a very important problem in rock hydraulics. On the basis of the experiment of a single fracture seepage,this paper proposed that the out of plane tortuosity be simulated by a sinusoidal seepage model and the in plane tortuosity by the seepage model of “carpet” cones. The statistical analysis of results of the experiment shows that the irregular fracture seepage has fractal effects.
