用微观分析和土工试验研究了含Ｎ的有机阳离子化合物对改善膨胀土性质的影响。研究结果表明，土体亲水性改变和强度提高都与该化合物能有效地与土颗粒进行阳离子交换并在颗粒表面形成吸附膜有关。此外，还对其应用可行性作了探讨
The effects of organic cationic compounds containing N on the properties of expansive soils were studied by means of microscopic analysis and geotechnical tests. The results show that both the hydrophilicity and the strength of the soil are related to the ability of the compound to effectively exchange the cation with the soil particles and form the adsorption film on the particle surface. In addition, the feasibility of its application is also discussed
