      摘要:
      為研究多年凍土隧道結構、圍巖的凍融變形規律以及含水量對隧底圍巖凍融循環次數和變形的影響365英超体育投注,本文采用有限元方法進行數值模擬365英超体育投注,采用熱-力場耦合計算隧道、圍巖的傳熱變形過程。計算結果表明:在運營期內,隧底凍土圍巖及路面的融沉位移逐年減小,總體呈現向上回升趨勢;凍結期隧底圍巖的回凍變形減輕了融沉變形導致的隧道不均勻變形程度,因此應重點控制施工期內隧底圍巖的融化沉降,加強隧底保溫措施以減少圍巖在運營期所經歷的凍融循環次數;凍土圍巖含水量越高365英超体育投注,運營期內隧底凍土回凍速度越快,隧底圍巖含水量超過27%時,融沉所導致的路面橫向不均勻融沉變形將對路面的排水帶來不利影響365英超体育投注365英超体育投注。
