一维溶质运移的参数研究

Parametric Study of One-dimensional Solute Transport

提出了有关超孔隙水压耗散对粘土中一维溶液对流-扩散溶质运移的影响的计算公式,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对流运移影响。并且论述了超孔隙水压力造成的耗散、外部荷载引起的吸出以及水头梯度的对土体体积变形影响,还着重探讨了有关溶质运移过程中固结、膨胀造成的水头、运移速度的不稳定变化的影响因素。

Formulation for the effect of dissipation of excess pore water pressure on one-dimensional advectivediffusive transport of solutes in clays was presented. The formulation was based on the effect of the rate of consolidation or swelling and excess pore pressure or suction dissipation on nonlinear advective component of transport through clay. The effects of dissipation of excess pore water pressure of suction as a result of external load or gradient application, the papers is focused on the effect of transient changes the hydraulic head and nonlinear advective velocity profile during consolidation or swelling on solute transport, assuming infinitesimal strain.
