大跨度连续刚构桥悬浇阶段的温度效应研究

Study of Temperature Effect of Long-span Continuous Rigid Frame Bridge during the Cantilever Construction

以洪屋涡特大桥为工程背景,介绍了温度场实验的方法,在有限元分析软件计算的基础上,分析了箱梁内部的温度分布以及挠度和应力随温度的变化规律。

Hongwuwo super span bridge is chosen as the background,the experimental method of temperature field is introduced.Based on the calculation of the finite software,the temperature distribution of the box-girder as well as the affect on deflection and strain of this bridge changing with temperature was analyzed.
