| 摘 要： | 土体的同结压缩变形对污染物的运移具有重要的影响,而目前国内关于污染物在变形多孔介质中运移规律的研究尚处丁空白,在国外也是近几年才有人开始这方面的研究工作.在Biot固结理论和污染物运移理论相结合的基础上,提出了污染物在黏土防渗层中迁移转化的一维数学模型,该模型的最大特点是考虑了土体受力变形对污染物运移的影响,在合理简化的基础上给出了模型的解析解,并将计算结果与太湖疏浚污染底泥堆场的实测结果进行了比较分析,模拟计算的结果在一定程度上能够反映实际土层中污染物的运移情况. |

| Abstract: | The consolidation behavior of cohesive soils has an important effect on the contaminant transport in a clay layer. In the current time the research on contaminant transport in deforming porous media has not yet begun in China; even in other countries this work only began some years ago. Combining Biot’s consolidation theory with the contaminant transport theory, a one-dimensional mathematical model for contaminant transport in clay layers is developed. The main feature of the model is considering the effect of soil deformation under loads on contaminant transport. The analytic solution of the model is then given based on some reasonable assumptions. Finally, the calculation results are compared with the results measured in a disposal site for the contaminated dredged sediments from the Taihu Lake. The simulated result has reflected the transport of contaminant in the actual soil layer. |
