乌鲁木齐城市道路粗粒土路基温度分布规律

Temperature Distribution Law of Coarse Soil Roadbed on Urban Roads in Urumqi

以乌鲁木齐市天山区典型城市粗粒土路基温度场的监测数据为基础,建立路基温度场的预估模型,研究城市道路路基温度变化规律及绿化带对路基温度的影响程度。结果表明:路基温度随时间的变化服从余弦函数分布;曲线峰值出现的时间随着深度的增加存在滞后性;绿化带的存在对路基温度场的分布规律具有一定程度的影响。

Based on the monitoring data of the typical coarse soil roadbed temperature field in Tianshan district of Urumqi City,an estimated model of roadbed temperature field is established,the study of the transformation law of urban roadbed temperature field and the degree of influence of green belt on roadbed temperature are carried out.The results show that the roadbed temperature obeys the cosine function distribution with the change of time;the time of curve peak appears lags with the increase of depth;the existence of green belt has some influence on the distribution law of the roadbed temperature field.
