摘要: 为了较准确地掌握桥面铺裴层温度场的分布规律,为温度应力计算及铺裴材料设计提供理论依据,从气象学和传热学基本原理出友,分析了影响桥面铺裴层温度场的环境因素,根据傅立叶传热定律导出了桥面铺裴层瞬态温度场的二维计算模型,采用ANSYS有限元软件对该模型进行了模拟分析,并将计算结果与实测结果进行比较.结果表明:在正确掌握边界条件及材料热物性参数的条件下,采用文中的计算模型可得到较为精确的数值解。

Abstract:

This paper aims to reveal the temperature distribution in the bridge deck pavement and to provide some theoretical guidelines for the calculation of temperature stress and the material design of the bridge deck pavement. In the investigation , the atmosphere factors that affect the temperature field of the bridge deck pavement are first an-alyzed based on aerography and calorifics theories. A two-dimension calculation model of the transient temperature field is established according to the Fourier heat-transfer law. Then , the proposed model is simulated using the fi-nite element software ANSYS. The obtained results are finally compared with those of the on-the-spot survey. It is concluded that , given the correct boundary conditions and thermo-physical parameters of the pavement material , the proposed model helps to obtain precise numerical solution.
