本文把路面看作为层状体系,根据传热学原理导出了气候条件下路面温度场的解析解,经验证与实际相符。文中所解决的层状半无限体在周期热力作用下的传热课题,为路面温度计算特别是分析不同基层对路面温度的影响提供了理论依据。同时,对其他与周期性温度波动有关的研究也具有一定参考价值。 In this paper, the pavement is regarded as a layered system. According to the principle of heat transfer, an analytical solution of the pavement temperature field under climatic conditions is derived. The heat transfer problem of semi-infinite layered body under periodic heat is solved in this paper, which provides a theoretical basis for the calculation of pavement temperature, especially the influence of different grass-roots on the pavement temperature. At the same time, it also has certain reference value to other studies related to the periodic temperature fluctuations.
