特大分离式双主肋主梁斜拉桥挂篮设计与仿真计算

摘要

Taking an extra -large separated double plane cable -stayed bridge with double -rib as the back- ground, the design scheme for suspended scaffolding at front point of support of the bridge with width of 35.5m and concrete weight of 430t at cast - in - place section of girder is emphatically introduced, and simulation analogue computation calculation on suspended scaffolding is made with finite element, and the safety of suspended scaffol- ding structure under different load is inspected.%以某特大分离式双主肋双索面斜拉桥为背景,重点介绍了桥宽35.5m、主梁悬浇段混凝土重量达430t的前支点挂篮设计方案,并用有限元对挂篮进行了仿真模拟计算,在不同荷载工况下检验了挂篮结构的安全性。
