钢桥面水泥混凝土-沥青复合铺装结构的温度场分析

Temperature field analysis of steel bridge deck concrete-asphalt composite pavement structure

桥面铺装是影响桥梁行车安全性、舒适性、桥梁耐久性以及投资效益的重要因素。文章针对桥面铺装体系容易出现的病害,提出了新型钢桥面轻质混凝土-沥青复合铺装结构,介绍了该复合铺装结构的温度场分布情况。通过在桥面铺装结构内部以及层间接触部位埋设的传感器,得到大量的实测数据,并在此基础上分析了钢桥面水泥混凝土-沥青复合铺装结构的温度场变化规律,为钢桥面力学特性分析提供依据。

The deck pavement is an important factor affects bridge traffic safety,comfort,bridge durability and investment efficiency.This paper aimed at deck pavement prone to diseases,put forward a new steel bridge deck lightweight concrete-asphalt composite pavement structure and introduced its temperature field distribution.It got a lot of measured data through the sensors buried in bridge deck pavement structure inside and contact area between the layers,and analyzed the temperature field change rule steel bridge deck concrete-asphalt composite pavement structure,which provides the basis for the mechanical properties analysis of steel deck.
