一般情况下 ,斜拉桥的合拢指的是梁与梁之间的合拢 ,即在主梁上预留一定长度的合拢段。公和斜拉桥根据该桥的施工特点 ,采用一种新颖的合拢方案 ,即在滑动模架上连续施工主梁 ,直到两边的主梁与边墩合拢。这种新方法的应用成功 ,为斜拉桥的施工方法及合拢方式的创新提供了宝贵的实践经验 Under normal circumstances, the cable-stayed bridge refers to the closure of the beam and the beam between the closure, that is, in the main beam to reserve a certain length of the closure segment. According to the construction characteristics of the bridge, the public and cable-stayed bridge adopt a novel closing scheme that the main girder is continuously constructed on the sliding formwork frame until the main girder and the side pier are closed on both sides. The successful application of this new method has provided valuable practical experience for the construction methods of cable-stayed bridges and the innovation of closing methods
