简要分析了桥面铺装层结构所处的环境情况与路面结构的区别,由于所处环境情况的差异使得桥面铺装层内表现出与路面结构不一样温度场分布。通过对乌鲁木齐市附近正在运营的某水泥混凝土桥面铺装埋设温度传感器,采集到了铺装层内的温度场分布的数据。根据采集到的大量数据,利用回归分析对桥面铺装层内不同深度处的温度场与大气温度关系进行回归,得出不同深度处温度与大气温度的关系。考虑大气温度与铺装层厚度对温度的影响,利用多元线性回归分析方法,得出铺装层内不同深度处温度与大气温度、铺装层厚度之间的关系。
The difference between the environment and the pavement structure of the deck pavement structure is briefly analyzed. Because of the difference of the environment conditions, the temperature distribution in the deck pavement layer is different from that of the pavement structure. The temperature field distribution in the pavement layer was collected by laying a temperature sensor on the pavement of a cement concrete bridge currently operating near Urumqi. Based on the large amount of data collected, regression analysis was used to regress the relationship between the temperature field and atmospheric temperature at different depths in the deck pavement, and the relationship between temperature and atmospheric temperature at different depths was obtained. Considering the effect of atmospheric temperature and pavement thickness on temperature, the relationship between temperature and atmospheric temperature and pavement thickness at different depths in the pavement layer was obtained by multivariate linear regression analysis.
