与多孔介质相比，裂隙介质中的渗流、溶质运移要复杂得多，许多学者在这方面进行了深入的研究，他们在模型的建立、求解、验证等方面都取得很大突破，但仍有许多难点没有解决。着眼于粗糙单裂隙开度变化的实质特性，将原有裂隙介质渗流、溶质运移方程进行修改，建立粗糙单裂隙渗流、溶质运移数学模型，并进行数值模拟。%Compare to the migration of seepage and solute of the porous rock mass, that of the single fractures is more complicated, many scholars has conducted in-depth studies in the field. Great breakthrough has been made in modelling, solving, proving while many difficulties have been left. Taking variations of fracture apertures into consideration, this study modifies the original equations about the migration of seepage and solute through porous rock mass, and builds a new one about the migration through rough single fracture, according to which numerical simulation is performed.
