摘　　要：结合工程实例,在分析连续梁挂篮施工中不同荷载组合的基础上,采用有限元软件MIDAS建立挂篮的整体模型,对挂篮施工中浇筑混凝土、空载前移与后退工况的抗倾覆安全性进行验算。根据计算结果对挂篮设计方案提出评价与建议,保证了挂篮在施工过程中的稳定性。Combined with specific project,and based on the analysis of different load combinations forced on the continious beam hanging-basket,the hanging-basket integral model was built by MIDAS.The anti-overturning safety was calculated for the conditions of pouring concrete and going ahead and back without load.According to the calculation result,the evaluation and suggestion for the hanging-basket design scheme were put forward, which could ensure the stability in hanging-basket construction.
