龙潭河大桥是一座连续刚构桥,主跨200 m,主墩高178 m。实测了太阳辐射下箱形墩和箱梁截面温度场,采用最小二乘法分析,获得了箱形墩顺桥向、横桥向与箱梁竖向、横向温差分布曲线。

Longtan River Bridge,which the main span is 200m and the main pier is 178m,is a long span continuous rigid frame bridge.Temperature field of box-pier and box-girder due to solar radiation was measured,regression analysis of the temperature difference using the least square method,and the fitting curve of vertical and transverse nonlinear temperature difference distribution of b...
