| 摘 要： | 在不同类型荷载作用下，双索面斜拉桥主梁不同位置的截面具有不同的应力分布规律。通过大比例模型试验与空间有限元分析结果的比较，得到了泸州泰安长江大桥箱形截面在几种典型荷载作用下的剪力滞系数，并对设计提出了几点建议。

| Abstract: | The rule of stress distribution is different on different cross sections of the girder of cable-stayed bridge with double cable planes under different type of loads.By comparing the results of large scale model test with that of spatial finite-element analysis,the coefficients of shear lag about the box section of Luzhou Tai'an Yangtze River Bridge under several typical loads are gained.Several suggestions are also put forward for designing. |
