| 摘 要： | 为分析高温差地区混凝土箱梁的温度场及温度效应,利用ANSYS通用有限元软件,建立了喀兰古大桥0#段有限元模型,分析了0#段在竖向温度梯度模式下的温度场分布规律及其温度效应。结果表明：箱梁结构内由于温度作用产生了较大的应力和位移,因此在高温差地区,该类结构在设计、施工时应考虑温度作用对结构产生的影响。

| Abstract: | In order to analyze the temperature field of and the temperature effects on box girder bridges in areas with great tem- perature difference,a finite-element model for the Kalangu Continuous Beam Bridge of the 0 # Section is established by means of the universal ANSYS finite-element-analysis software in the paper,with the distribution law of the temperature field of and the temperature effects on the 0# section in the vertical temperature gradient model analyzed. The results of the analysis show that relatively great temperature-change-caused stress and displacement emerge inside the box girder structure,owing to which the impact of the temperature has to be considered in the design and construction of this type of structures in areas with great temperature difference. |
