Abstract为分析深季节冻土区涵洞对路基及其下地基热状况的影响,建立了涵洞温度场计算模型,基于已有的试验涵洞监测数据,对比分析了所建模型的可靠性,再在该模型基础上,通过改变材料参数和模型尺寸,进行不同情况下的数值计算。结果表明:模拟季节冻土区涵洞温度场时,需要充分考虑热对流效果,忽略填土热对流效果是不合适的,考虑热对流效果的模型在定性和定量上均与现场监测情况一致;在季节性冻土区涵洞设计工作中,应该采取一些积极措施避免或减少对流传热对涵底冻深发展的影响;涵底最大冻结深度随着含水量呈三段式的变化规律:随其增大先减小,后减小速度变缓甚至冻深略有增加,最后又趋于减小;寒区涵洞内径的尺寸对涵底冻结深度方面的影响较大...
