内蒙古西部地区沥青路面温度场变化规律分析

Analysis on the Variation Law of Asphalt Pavement Temperature Field in Western Inner Mongolia

内蒙古西部区域面积大、地理条件复杂、气候条件特殊,对公路沥青路面结构设计有重要影响,为了能真实客观地了解内蒙古西部地区沥青路面结构温度的分布特征及其差异性,研究选择在鄂尔多斯、巴彦淖尔作为观测点埋设温度传感器,持续观测具有代表性的夏季和冬季路面结构内部温度。通过对沥青路面结构内部温度实测数据深入分析,得出了路面结构层内的高、低温温度分布规律,基于数据统计回归建立了温度场模型,为内蒙古西部地区路面结构设计提供依据。

The western region of Inner Mongolia has a large area,complex geographical conditions,and special climatic conditions,which have a significant impact on the design of highway asphalt pavement structure.In order to truly and objectively understand and study the distribution,characteristics and differences of the temperature of asphalt pavement structures in the western region of Inner Mongolia,this study selected Ordos and Bayannur as observation points to bury temperature sensors and continuously observe the internal temperature of representative pavement structures in summer and winter.Through in-depth analysis of the measured temperature data inside the asphalt pavement structure,the high and low temperature distribution laws within the pavement structure layer were obtained,and a temperature field model was established based on data statistical regression.The research results provide a basis for pavement structure design in western Inner Mongolia.
