　　本文选用三种不同粒径的标准砂作为充填裂隙、结合单裂隙圆管建立了单裂隙一维变密度水流模型，主要研究变密度水流运动中标准砂的渗透系数随浓度的变化规律以及变密度水流运动之后充填裂隙的渗透系数变化规律。本文成果对实际工程中的水污染治理具有重要的理论意义。

A single fracture of one-dimensional variable density flow model is established with three different sizes standard sand as filling cracks and a single crack pipe in this paper. It is in order to study the connection law of the permeability coefficient of the standard sand with the concentration. This paper has important theoretical significance on water pollution control in practical engineering.
