摘要

针对多年冻土区路基路面病害多发的现状，从路面材料入手，对水泥混凝土和沥青两种路面下路基温度场的变化规律进行研究。研究结果表明，在计算高度范围内，对于8.5 m路面宽幅的路基来说，沥青路面下的最大融深大于混凝土路面下的最大融深，尤其在路基高度较低时两种路面下的融深差异更大。最大融化深度和最大融化深度发展速率均与路基高度和路面宽幅有紧密关系，通过研究可以提出有效的措施来保持路基热稳定性，从而减少路基路面病害的发生和公路的运营成本，为今后类似工程提供参考

Abstract

Temperature field under highway embankment were studied respectively for concrete pavements and asphalt pavements by finite element method against the presences of large amounts of occurrent pavement diseases in permafrost region. The results of numerical analysis indicate that the maximum thawed depth under embankment of asphalt pavements is greater than the one of concrete pavements; and especially the maximum thawed depth differences between asphalt pavement and concrete pavement become greater under pavements for the embankment of 8.5m width. Both the maximum thawed depth and development rate of the maximum thawed depth are closely relevant to embankment heights and embankment widths. The effective measurements will be proposed to keep the thermal stabilities of highway embankment by the results and cut down the occurrences of pavement diseases and services costs. The results may also provide references for the future similar projects.
