摘要
以钢管混凝土拱桥拱肋截面的温度场为分析对象,以热传导理论结合有限元通用程序ANSYS进行数值分析。分析钢管截面尺寸,混凝土浇筑温度等参数对钢管混凝土浇筑初期的截面温度分布的影响。为便于分析,切实模拟,做出了适当的假定,采取了合适的分析参数。分析方法可以推广到实际工程,并为实际工程的理论分析提供参考。
The temperature field of concrete filled steel tubular (CFST) arch bridge is analyzed, by means of the heat conductivity theory and finite element method, an analytic model is developed for the arch rid. In which several factors having on the temperature distribution, such as steel thickness, diameter of tube and placing temperature of concrete, has been considered. In order to simplify the analysis, simulate the actual situation, has made the suitable supposition and adopted the appropriate analysis parameters. It could spread to practice project and provide reference for theory analysis.
