摘要
Through a long-term summary of highway construction in the permafrost regions of Qinghai Province, the formation conditions and distribution characteristics of permafrost and their impact on transportation construction are analyzed. Research achievements on the stability of highways and urgent technical problems in the transportation construction in permafrost regions are discussed, and new development directions of highway construction in permafrost regions of Qinghai Province are introduced to provide cold regions engineering researchers with valuable references.
