| 摘 要： | 以一座33．0m宽的单索面矮塔斜拉桥为背景，索力为对象，研究了宽箱梁的空间应力分布，总结了其分布特征及影响其分布的因素。对基于平面杆系的设计理论，以此指导截面配筋，可使宽桥的截面应力更均匀。

| Abstract: | Based on a 33.0 meter wide extradosed cable-stayed bridge with single plane cables , the distribution of spatial stress in wide box-girder is studied on cable force. Then its law of distribution and influence factors are concluded. It can be used to dispose prestressing steels on section ,and make the stress on section more smooth, which is meaningful. |
