| 摘 要： | 龙潭河大桥是一座高墩大跨径连续刚构桥,其最大跨径200 m,实测了太阳辐射下箱梁截面温度场,采用最小二乘法对实测温差进行回归分析,获得了箱梁竖向温差、横向温差非线性分布的拟合曲线。建立该桥的有限元计算模型,并分析了横向温差的影响。

| Abstract: | Longtan River Bridge is designed as a high pier and long span continuous rigid-frame bridge with its longest span reaching 200 m.Temperature field of box-girder due to solar radiation was measured,a regression analysis of the temperature difference using the least square method,and the fitting curve of vetical and horizontal nonlinear temperature difference distribution of box beam that in the sunshine are obtained in this paper.A calculation model for the bridge using finite element method has been built,a... |
