摘要

【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。

Abstract

[Objective] With the large-scale development of China's infrastructure construction, the scale and depth of highway soft soil foundation treatment have been greatly improved in recent years, and new theories, new technologies, new materials and new processes of highway soft soil foundation treatment haveemerged constantly and been popularized and applied in engineering practice. In order to avoid blind selection of highway soft soil foundation treatment technologies, and make mature, reliable, cost-effective technical achievements more widely promoted and applied, it is necessary to timely update and summarize the current research progress of highway soft soil foundation treatment technology.[Methods] On the basis of combing the development period of highway soft soil foundation treatment technology in China, a variety of characteristic and representative new technologies developed in highway soft soil foundation treatment in recent years are classified from four aspects: drainage consolidation method, composite foundation method, replacement method and curing agent stabilization method, and some theoretical achievements and standardization of highway soft soil foundation treatment technology are summarized. At the same time, the shortcomings and future development trend of highway soft soil foundation treatment technology are put forward.[Results] The research shows that based on China's national conditions and the needs of social and economic construction, the development period of highway soft soil foundation treatment technology is reasonably divided into four stages(initial exploration stage → vigorous development stage → diversified innovation development stage → green and low-carbon development stage). Although the overall level of China's highway soft soil foundation treatment technology has been greatly improved, but with the scale and depth of China's soft soil foundation treatment has been greatly improved, it is still facing more and more challenges, such as the limited development of construction machinery, the technical construction and monitoring is not intelligent enough, the service toughness needs to be improved, the safety, environmental protection and economy are not enough.[Conclusion] combined with the national requirements for intelligent construction and environmental protection and energy saving, China's highway soft soil foundation treatment technology will continue to develop in the direction of multi-method combined technology, intelligent construction, intelligent operation and maintenance technology, high value utilization technology of green and low-carbon, standardized technology system in the future. The research result will point out the direction and provide reference for the treatment technology of highway soft soil foundation in China at present.
