摘要: 为了准确预估路面结构温度场,对云南省某高速公路沥青路段进行了为期一年的气温及路面结构内温度场数据采集;根据实测的气温数据,在双正弦函数模型的基础上,考虑太阳辐射角年周期变化对气温的影响,建立了修订双正弦函数模型,并将修订前后的双正弦函数模型的计算值与实测数据进行了对比分析;基于修订双正弦函数模型,考虑热传递损耗以及滞后性,建立了以平均气温、气温振幅为依据的沥青路面晴天日温度场模型,并对沥青路面晴天日温度场模型的计算结果和实测数据进行了对比分析。研究表明:修订双正弦函数模型以及沥青路面晴天日温度场模型均有较高的计算精度;沥青路面晴天日温度场模型的计算结果可以较好地反应不同月份沥青路面温度场的变化规律,可为沥青路面温度应力研究以及沥青路面设计提供参考。

Abstract: In order to accurately predict the temperature field of pavement structure, a year-long data acquisition of temperature and temperature field in pavement structure of an expressway in Yunnan Province was carried out. Based on the measured temperature data and the double sinusoidal function model, a modified double sinusoidal function model was established with considering the influence of annual variation of solar radiation angle on temperature. Comparisons between the calculated values and the measured data of double sinusoidal function model before and after modifying were carried out. Based on the modified double sinusoidal function model, considering heat transfer loss and hysteresis, a sunny temperature field model of asphalt pavement was established, which was based on the average air temperature and air temperature amplitude. The calculated results and measured data of the sunny temperature field model of asphalt pavement were compared and analyzed. The results show that both the modified double sinusoidal function model and the sunny temperature field model of asphalt pavement have high accuracy. And the calculation results of the sunny temperature field model of asphalt pavement can better reflect the changing law of temperature field of asphalt pavement in different months, which can provide reference for the research of temperature stress of asphalt pavement and the design of asphalt pavement.
