The seepage of remolded loess with inorganic salt solutions can deteriorate its engineering properties. To gain insight into the mechanism responsible for changes in the permeability of remolded loess due to the invasion of inorganic pollutants, the saturated permeability tests were performed on remolded loess samples using deionized water (DW) and NaCl, CaCl₂, AlCl₃, and NaHCO₃ solutions. Leaching tests were designed to determine the chemical components of leachates. Zeta potentials were measured to evaluate the electrochemical properties, and mercury intrusion porosimetry (MIP) and scanning electron microscope (SEM) tests were used to estimate changes in microstructure before and after seepage. The results indicate that the saturated hydraulic conductivity (K_sat) was positively correlated with the cation valence. With the increase of cation valence, the compression degree of double diffusion layer on the surface of clay particles increases, and a larger space for free water movement is formed. The salt effect promoted the dissolution of carbonate minerals of loess and enhanced permeability, for example, NaCl; while the common-ion effect of HCO₃⁻ inhibited their dissolution and even led to the calcite precipitation. In addition, the hydrolysis of Al³⁺ also significantly affected K_sat. Therefore, under the seepage of inorganic salt solutions, the order of K_sat of remolded loess samples was NaHCO₃ < DW < NaCl < CaCl₂ < AlCl₃.

用无机盐溶液渗入改造黄土会使其工程性能恶化。为了深入了解无机污染物侵入改造黄土渗透率变化的机制，采用去离子水(DW)和NaCl、CaCl ₂、AlCl ₃和NaHCO对改造黄土样品进行饱和渗透率测试。₃解决方案。浸出试验旨在确定浸出液的化学成分。测量 Zeta 电位以评估电化学性能，并使用压汞孔隙率 (MIP) 和扫描电子显微镜 (SEM) 测试来估计渗流前后微观结构的变化。结果表明，饱和导水率（K _sat）与阳离子化合价呈正相关。随着阳离子化合价的增加，粘土颗粒表面双扩散层的压缩程度增大，形成更大的自由水运动空间。盐效应促进了黄土碳酸盐矿物的溶解，增强了渗透性，如NaCl；而 HCO ₃的共离子效应^-抑制了它们的溶解，甚至导致方解石沉淀。此外，Al ³⁺的水解也显着影响K _sat。因此，在无机盐溶液的渗流作用下，重塑黄土样品的K _sat顺序为NaHCO ₃  < DW < NaCl < CaCl ₂  < AlCl ₃。
