摘要:
提出了有关可变形多孔介质溶质运移的的计算公式,该公式考虑了固结速率、膨胀速率、超孔隙水压力、吸出耗散等对非线性平流运移影响.用3种假设案例来说明透水黏土层中固结、膨胀、超孔隙水压力等对溶质运移过程以及临界点的影响,结果表明黏土层中固结影响浓度分布,但是并不显著影响运移通量的最大值,固结作用加速运移过程,不同的水头梯度下引起的膨胀能否加速平流运移过程,取决于有效扩散系数与固结系数的比值.
Abstract:
A calculation formula for solute transport in deformable porous media is proposed, which considers the effects of consolidation rate, expansion rate, superpore water pressure, and suction dissipation on nonlinear advection transport. Three hypothetical cases were used to illustrate the effects of consolidation, expansion and superpore water pressure on the solute transport process and critical point in the permeable clay layer, and the results showed that consolidation in the clay layer affected the concentration distribution, but did not significantly affect the maximum value of the transport flux, the consolidation accelerated the transport process, and whether the expansion caused by different head gradients could accelerate the advection transport process depends on the ratio of the effective diffusion coefficient to the consolidation coefficient.
