摘　　要：为了研究新疆阿勒泰地区的附面层参数,基于第二类和第三类混合边界条件,综合考虑太阳辐射、路面辐射、对流换热和蒸发耗热等因素的影响,运用数值模拟软件建立该地区季节冻土路基温度场模型,研究了新疆阿勒泰地区季节冻土路基温度场附面层参数及温度函数。研究结果表明:新疆阿勒泰地区天然地面的附面层厚度为0.4m,附面层底温度初始值为9.61℃,振幅为14.56℃;沥青面层附面层厚度为0.45m,附面层底温度初始值为10.85℃,振幅为16.43℃;混凝土面层附面层厚度为0.45m,附面层底温度初始值为9.46℃,振幅为16.39℃。In order to study the boundary layer parameters in the Altay region of Xinjiang,based on the mixed boundary conditions of the second and third types,taking into account the effects of solar radiation,pavement radiation,convective heat transfer,and evaporation heat consumption,a numerical simulation software was used to establish a temperature field model for the seasonally frozen subgrade in the region,and the boundary layer parameters and temperature functions of the seasonally frozen subgrade in the Altay region of Xinjiang were studied.The results show that the thickness of the boundary layer on the natural ground in Altay,Xinjiang is 0.4m,the initial temperature of the boundary layer bottom is 9.61℃,and the amplitude is 14.56℃.The thickness of the asphalt surface layer is 0.45m,the initial temperature at the bottom of the surface layer is 10.85℃,and the amplitude is 16.43℃.The thickness of the concrete surface layer is 0.45m,the initial temperature at the bottom of the surface layer is 9.46℃,and the amplitude is 16.39℃.
