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200m,实测了太阳辐射下箱梁和高墩截面温度场,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、横向温差和桥墩顺桥向、横桥向温差非线性分布拟合曲线。

摘  要:
Longtan River Bridge is designed as a high pier and long span continuous rigid-frame bridge with its longest span reaching 200 meters.Temperature field of box-girder and high pier due to solar radiation was measured,a regression analysis of the temperature difference using the least square method,and the fitting curve of vertical and horizontal nonlinear temperature difference distribution of box beam and tall pier that in the sunshine were obtained.
