| 摘 要： | 佛山东平大桥采用带副拱的自平衡体系转体施工,成桥后未拆除副拱结构。通过对副拱荷载行为的研究,得出如下结论:东平大桥副拱的存在可减小主拱的恒、活载应力和挠度,降低刚性系杆的张拉力,改善结构频率分布,减少振型激起,合拢后对结构受力有益,应不予拆除。 |

| Abstract: | The swing-body method was applied to the construction of Dongping Bridge in Foshan adopted a self-balance system of plane-rotation with subarch which remains as permanent constituent of the bridge after the construction. Through the research on subarch load behavior some conclusions drawn are as follows: the subarch not only reduces deflection caused by dead loads and live loads and tensioning force of rigid tie but also improves frequency distribution to decrease vibration arose. The service behaviors of D... |
