我国多年冻土地区的路基修筑技术及其相关研究走过了50年的历程。从多年冻土地区路基修筑技术的回顾出发,系统总结了多年冻土地区路基冻胀、融沉和纵向裂缝等主导病害的发育性状、分布规律和形成机理,就基于多年冻土稳定的路基设计理论和面向调控的路基稳定结构进行了深入探讨,最后提出了路基修筑技术未来的发展趋势。
Subgrade construction technology and its related research in permafrost regions in China have gone through 50 years. Based on the retrospect of subgrade construction technology in permafrost regions, the development characters, distribution rules and formation mechanism of the main diseases such as frost heave, thaw sinking and longitudinal cracks in permafrost regions were systematically summarized. Based on the roadbed design based on the stability of permafrost Theory and regulation-oriented subgrade stability structure were discussed in depth, and finally proposed the future development trend of subgrade construction technology.
