| 中文摘要: |
| 结合朝天门长江大桥主跨合龙特点介绍主跨合龙的思路、计算及操作要点，应用大型有限元分析程序MIDAS建立了朝天门长江大桥的三维有限元简化计算模型，并对其进行了施工过程控制分析。大桥的建模可以为同类桥梁的施工控制提供有益的思路。 |
| 英文摘要: |
| Based on the closure character of Chaotianmen bridge, the procedure, calculation and major operation of main span closure are introduced.Three-dimensioned finite element simplified model of Chaotianmen bridge is established using MIDAS, and the construction process control is also analyzed.The research results can be taken as reference to similar bridge. |
