摘要(Abstract)：

【目的】随着我国基础设施建设的大规模开展，近年来公路软土地基处理规模和深度大幅提高，公路软土地基处理新理论、新技术、新材料、新工艺不断涌现并在工程实践中得到推广应用。为了避免盲目选取公路软土地基处理技术，使成熟可靠、经济高效的技术成果得到更加广泛的推广应用，有必要及时更新和归纳总结现阶段公路软土地基处理技术相关研究进展。【方法】在梳理我国公路软土地基处理技术发展历程的基础上，从排水固结法、复合地基法、置换法和固化剂稳定法四个方面分类阐述了近年公路软土地基处理发展起来多种极富特色且具有代表性的新技术，总结了公路软土地基处理技术若干理论成果和标准化建设情况，并提出了现阶段公路软土地基处理技术存在的不足和今后发展趋势。【结果】研究表明，基于我国国情和社会经济建设的需要，我国公路软土地基处理技术经历了从初步探索→蓬勃发展→多元化创新发展→绿色低碳发展四个阶段的发展；尽管我国公路软土地基处理技术整体水平较之前有了较大的提高，但随着我国软土地基处理规模和深度大幅提高，仍面临越来越多的挑战，例如施工机械水平限制发展，技术建造与监测不够智能化，服役韧性有待提高，安全性、环保性和经济性不够。【结论】结合国家对建造智能化及环保节能的要求，未来我国公路软土地基处理技术将持续向多方向联合技术、智能建造及智慧运维技术、绿色低碳高值化利用技术、规范化与标准化技术体系等方向发展。研究成果将为现阶段我国公路软土地基处理技术指明方向和提供参考。
