斜拉桥因为其本身存在着跨越能力高、造型优美、耐久性好的施工优势在近几年得到飞速发展。但是在施工的过程中,因为主梁施工工序对叠合梁斜拉桥施工阶段、成桥阶段以及运营阶段的内应影响很大,一旦施工技术不合理、施工控制不科学,很容易造成桥梁面板产生裂缝,因此在工程施工总必须要对施工工序和施工方案进行严格的分析和探索。结合工程实例,探讨了叠合梁斜拉桥施工工序方案,探讨了其有关施工技术要点。
Cable-stayed bridges have enjoyed rapid growth in construction in recent years due to their high leaping capacity, graceful appearance and good durability. However, during the construction process, because the main girder construction process has a great influence on the internal construction of the composite girder cable-stayed bridge during the construction phase, the bridging phase and the operation phase, once the construction technology is unreasonable and the construction control unscientific, it is easy to cause the bridge panel Resulting in cracks, so in the construction must always be on the construction process and construction programs for rigorous analysis and exploration. Combined with engineering examples, the construction process of the composite girder cable-stayed bridge is discussed, and the key points of construction technology are discussed.
