摘要
将观测尺度降低到小时,对晋北地区气温变化特征进行了分析,揭示了寒区隧道在年度周期内经历的多频次短周期冻融循环特征,并探讨了其对寒区隧道混凝土材料和衬砌结构防冻的影响。
This paper analyzed temperature variation characteristics in north Shanxi area, revealed the multifrequency and short cycle freeze-thaw cycle characteristics that cold regions tunnel experienced in the annual cycle. It also discussed the influence on cold regions tunnel concrete materials and lining structure anti-freezing.
