| 摘 要： | 关门山大桥加固方案采用体系转换,即把双悬臂带挂梁的组合梁桥改变为连续梁桥,但体系转换后,为满足结构纵向变位的需要,在各墩顶需进行支座更换,更换支座需顶升主梁,对更换支座状态下墩顶横隔梁的受力分析及设计进行了详细介绍。

| Abstract: | The Guanmenshan Bridge is reinforced by system transformation,that is to convert the composite beam bridge with double-cantilever-beam and suspended beam into the continuous beam bridge.But after the system transformation,the bearing should be replaced at the pier top to meet the needs of longitudinal elongation of structure.The main girder should be lifted up to replace the bearing.In the state of bearing replacement,force analysis and design of pier diaphragm are introduced in detail. |
