摘　　要：基于ORIGN软件对新疆伊犁试验路采集的温度数据进行分析,研究温度与时间、路基深度的关系。结果表明:高斯公式可作为伊犁地区月平均温度与时间的数学模型;通过温度与地基深度关系数据分析可得,随着土壤深度的增加,地温最高值或最低值出现的时间逐渐延迟。高温季节温度随深度的增加线性递减,低温季节温度随深度的增加线性递增,可采用直线式作为该地区温度与路基深度的数学模型。Based on the ORIGN software＇s analysis of the temperature data collected in the Xinjiang Yili test road,this paper studies the relationship between temperature, time and roadbed depth. The result shows that gauss formula can be used to establish mathematical model of monthly mean temperature and time in Ili. According to the temperature and soil depth data, it is concluded that with the increase of soil depth, the maximum and minimum temperature delay to appear. During the high-temperature season, the underground temperature decreases with depth linearly, while it increases with depth during the low-temperature season.And the straight line type can be the temperature and depth of subgrade mathematical model in this area.
