摘要
某大桥主桥梁部为70-110-110-70m悬浇预应力混凝土变截面连续箱梁,边跨和中跨合拢,结构先后完成2次体系转换。文章重点介绍合拢段受力分析与劲性骨架设计。
The main span of a bridge constitutes of four 70-110-110-70 meters long cantilever beams. The structure has finished system transfer twice during the closure of side span and the closure of mid-span. The article mainly presents the stress analysis and stiff skeleton design at the closure, sector.
