| 中文摘要: |
| 以晋蒙黄河大桥工程为背景，讨论了不同合龙顺序对长联大跨低墩刚构 连续梁组合梁桥的受力影响，并针对该类桥梁提出了科学合理的合龙顺序确定原则。按照该原则确定合龙顺序可使主梁在运营状态下受力更为均匀合理，对类似桥梁合龙顺序的确定具有一定的参考价值。 |
| 英文摘要: |
| Based on Jinmeng Yellow River Bridge, the influence of different closure sequences on final inner force status of long unite and large span rigid frame and continuous beam combination bridge is discussed. The principle of determining the rational closure sequence is proposed for such kind of bridge. With the rational closure sequence determined by this principle, the stress states of the main girder can be more reasonable. This principle has reference value for the similar structure. |
