摘要:
Up to date, there are still few reports on the study of solute transport in deforming soils. However, the loading must be considered in practical engineering. Based on the Biot s consolidation theory and the solute transport theory, the solute transportation model with coupled seepage field, stress field and concentration field was established, and then the finite difference method was used to simulate the solute migrating process in the deforming soils. In addition, when studying the solute migrating process, many scholars generally adopt the linear adsorption mode to describe the adsorption property of soil. Because the fine-grained soils always exhibit strong non-linear sorption to metal ions, organic matters or highly concentrated solution, the migrating process of solute under different adsorption mode was analyzed. The results show that the consolidation deformation has a permanent retarding effect on the transport process of solute, which leads to the decrease of transport depth of solute. The adsorption mode does not have the essential influence on the transport law of solute, but it has apparent impact on the transport velocity of solute, and moreover the influence gradually increases with time.
