为分析温度场对沥青路面的影响,依托新郑高速的气温数据,采用ABAQUS有限元分析软件,建立了夏季沥青路面温度场模型,研究了路面结构深度与太阳辐射时间对路面温度场的影响,通过变化材料热物理参数研究路面温度场随材料热物理参数变化的规律。结果表明:路面结构对环境温度的变化有消减作用;路面结构内部温度响应受环境温度影响,同时具有衰减性与滞后性;路面温度随导热系数、比热容的增大而降低,却随导温系数的增大而升高;材料热物理参数中导温系数对路面温度场的影响最大,比热容的影响最小,导热系数介于中间。

In order to analyze the influence of temperature field on asphalt pavement, the temperature field model of asphalt pavement in summer was established by using ABAQUS finite element analysis software based on the temperature data of Xinzheng Expressway and the influence of pavement structure depth and solar radiation time on the temperature field of pavement was studied. The variation of the temperature field of pavement with materials was studied by changing the thermophysical parameters of materials. The results show that the pavement structure has a reducing effect on the change of ambient t...
