| 摘 要： | 以一座27．0 m宽的单索面矮塔斜拉桥为例，研究了拉索在宽幅箱梁中的传递规律。研究发现剪力滞现象十分严重，并且随着箱梁的宽度的增大而更加严重，在布置预应力筋时要引起充分重视，以使宽桥的截面应力更均匀。

| Abstract: | The transferred rule of cable force in the wide box girder is studied by instance of single extradosed cable-stayed bridge with 27 m wide. It is indicated that the phenomenon of shear lag is very severe. And the phenomenon of shear lag is more and more severer along with the increase of the wide box girder. The phenomenon must be considered fully in order to uniformity of the section stress in the wide bridge. |
