摘要
采用细砂(粒径约2mm)均匀填充土柱,用配置的与煤系矿坑水成份相似的淋滤液进行扰动土柱试验.通过对试验过程及穿透数据的分析,建立了一个描述淋滤液中各离子迁移行为的数学模型,并应用一种最佳摄动量迭代算法对未知的模型参数进行了数值反演模拟.结果表明,所用算法对于文中扰动土柱试验模型的参数反演是有效的.
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 .
