英文摘要：

By filling fine sands with diameter of 2mm into a column uniformly, and infiltrating with artificial coal-mine water from the top of the column, the disturbed soil-column experiment was carried out and 23 water samples were collected at the bottom of the column. Based on the analysis of the experimental processes and the measured breakthrough data, a mathematical model describing transport behaviors of the solute ions in the column was established. Furthermore, numerical simulations for the unknown parameters inversion were carried out by applying an optimal perturbation iteration algorithm. These results show that the optimal perurbation iteration algorthm is efficient to the parameters inversion for the disturbed soil-column experiment .
