Polymer soil stabilisers have been shown to improve soil strength and erosion resistance, for example on slopes where topsoil can be easily eroded. However, fundamental mechanisms of soil stabilisers in soil enhancement through modifying the soil-water characteristic and microstructure of soil (e.g., distribution of pore size) have not been fully understood. This gap in understanding is not conducive to the subsequent development and engineering applications of soil stabilisers. This paper reports a series of experimental studies on the influence of nano-aqueous adhesive (NAA) in modifying the pore size distribution and water content of the soil. The results show that NAA can change the soil-water characteristic curve and has the potential to increase water retention capacity, which is essential for vegetation growth on a slope. In addition, they indicate that NAA could improve soil microstructure and pore uniformity by blocked small pores. The results also show that the NAA could reduce wilting coefficient, improve air entry value, and thereby protect vegetation, which helps stabilise the slope.

聚合物土壤稳定剂已被证明可以提高土壤强度和抗侵蚀性，例如在表土容易被侵蚀的斜坡上。然而，土壤稳定剂通过改变土壤水特性和土壤微观结构（例如，孔径分布）来增强土壤的基本机制尚未完全了解。这种认识上的差距不利于土壤稳定剂的后续开发和工程应用。本文报道了一系列关于纳米水性粘合剂 (NAA) 在改变土壤孔径分布和含水量方面的影响的实验研究。结果表明，NAA 可以改变土壤-水特征曲线，并具有增加保水能力的潜力，这对于坡地植被生长至关重要。此外，他们表明 NAA 可以通过堵塞小孔隙来改善土壤微观结构和孔隙均匀性。结果还表明，NAA可以降低萎蔫系数，提高空气进入值，从而保护植被，有助于稳定边坡。
