| 摘 要： | 以重庆菜园坝长江大桥为例,利用有限元方法研究了大跨径拱与Y型刚构组合桥的横向联结系、横撑刚度对全桥稳定性的影响。结果表明,横撑的布置方式直接影响拱式组合体系的稳定性,而横撑刚度对全桥稳定性的影响不大。 |
| 关 键 词： | Y型刚构 横向联结系 横撑 稳定性 |

| Abstract: | In this paper, taking Chongqing CaiYuanBa Yangtze Bridge as an example, the finite element method was used to study the effect of lateral coupling systems and braces on full bridge stability for combination bridge of long-span arch and Y-style frame. The results show that the set of lateral braces has direct influence on stability of arch-style combination system, while the influence of lateral brace rigidity is slight. |
| Keywords: | Y-style frame lateral coupling system lateral brace stability |
