[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0023] figure 1 It is a flowchart of a method for evaluating the migration characteristics of pollutants in rough single cracks without filling in the present invention; the present invention proposes a method for evaluating the migration characteristics of pollutants in rough single cracks without filling, which is characterized in that it specifically includes : Firstly, determine the type and solubility of pollutants, and distinguish them into soluble pollutants and non-aqueous liquid pollutants; secondly, use fractal theory to establish a rough single-crack model; thirdly, establish a rough single-crack numerical model without filling based on the finite element method; Finally, the convect...
