| 摘 要： | 主要讨论了一维土柱试验模型及其反问题.考虑到溶质在土壤及地下水中迁移的非线性行为,认为通常模型中的阻滞因子应改为与溶质浓度相关的泛函,而零阶产出项应为与时间、空间及溶质浓度相关的非线性项,进而提出了一类新的描述一维土柱试验的非线性数学模型.对于模型参数的识别问题,给出了两类典型的确定阻滞因子与源(汇)项系数的土柱试验反问题.最后,以淄博张店孝妇河-张冉原状土柱试验为例,应用所建立的数学模型对试验结果做了初步的阐释.

| Abstract: | One-dimensional soil-column experiment models and inverse problems are discussed in this paper.Due to nonlinear behaviors of solute transport in soil and groundwater,the ordinary retardation factor should be a nonlinear function of solute concentration,and the zero production term should be modified to a nonlinear term related with solute concentration,and then a new mathematical model with nonlinear terms is proposed.Furthermore,two kinds of inverse problems for soil-column experiments are discussed.Finally,an original soil-column experi ment in Zhangdian of Ziboisinvestigated,and a reasonable explanationforthe testing results is obtained with the help of the mathematical model. |
