摘要
盐渍土因其独特的盐胀、溶陷和腐蚀特性,在工程应用中面临诸多挑战,众多学者针对盐渍土强度的影响机理进行了深入研究.文中综合分析含盐量、冻融循环及固化剂等对盐渍土强度的影响,揭示了这些因素影响盐渍土强度特性的机理.尽管已取得一定进展,但固化盐渍土的研究仍存在一些不足.此外,文中还对固化盐碱土的未来发展进行了展望,并提出利用绿色废料固化盐碱土的研究方向,旨在推动该领域的可持续发展.
Abstract
Salt-affected soils present unique challenges in engineering applications due to their swelling,dissolution,and corrosive properties.In light of this,many scholars have conducted in-depth studies on the mechanisms affecting the strength of salt-affected soils.This paper com-prehensively analyzes the effects of factors such as salt content,freeze-thaw cycles,and stabilizing agents on the strength of salt-affected soils,revealing the mechanisms by which these factors influence the strength characteristics of salt-affected soils.The research finds that although some progress has been made,there are still some deficiencies in the study of stabilized salt-affected soils.The paper also looks forward to the future development of stabilized saline-alkali soils and proposes research directions for the use of green waste materials to stabilize saline-alkali soils,aiming to promote sustainable development in this field.
