摘　　要：软土地基承载力低是基础工程中的重要挑战,利用土壤固化剂进行软土加固已成为国内外学者研究的热点领域。文章系统回顾了各种固化剂的发展历程,归纳了其作用机理,并探讨了影响固化土力学性能的关键因素。研究发现,软土固化剂的发展呈现出从单一材料向多元化、从简单应用向专业化和标准化、从污染耗能向绿色节能的演变趋势。此外,研究表明,增加固化剂掺量和延长龄期有助于提升固化土的强度,而较高的土壤含水率和有机质含量则对强度产生负面影响。The low bearing capacity of soft soil foundations is a significant challenge in foundation engineering.The chemical stabilization of soils using soil stabilizers has become a major focus of research for scholars both domestically and internationally.This paper systematically reviews the development history of various stabilizers,summarizes their mechanisms of action,and explores the key factors influencing the mechanical properties of stabilized soils.The findings reveal that the development of soft soil stabilizers is characterized by a shift from single-material to multi-component formulations,from simple applications to specialized and standardized practices,and from pollutionintensive to environmentally sustainable approaches.Furthermore,it is demonstrated that increasing the stabilizer dosage and curing time enhances the strength of stabilized soils,whereas higher soil moisture content and organic matter negatively impact strength development.
