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.

Key words: consolidation, compression deformation, porous medium, contaminant transport, model
