乌鲁木齐地区水泥混凝土桥面沥青铺装层温度场分析

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。

Analysis of Temperature Field of Asphalt Mixture Bridge Deck Pavement on Cement Concrete Bridge in Urumqi

The difference between the bridge deck pavement structure and road structure in environment was analyzed briefly.Because of the different environmental conditions made the different distribution of temperature field between bridge deck pavement structure and road.The dates of bridge deck pavement temperature distribution was collected through buried some temperature sensors in cement concrete bridge deck pavement near the city of Urumqi.The datas was analyzed by use of regression analysis,and the relations between the temperature field of different depth of bridge deck pavement and air temperature was established.Considering the influence of the air temperature and the pavement layer thickness,predicted the temperature of bridge deck pavement with air temperature and thickness through multiple linear regression analysis.
