摘　　要：碗扣式钢管支架在现浇桥梁施工中的应用越来越多,通过对其受力状况的研究,并结合工程实践,运用MIDAS/Civil分析软件建立了钢管支架的空间计算模型,并进行了承载力、稳定性、地基承载力验算,为施工过程提供技术支持,对此类结构的钢管支架设计和施工提供了借鉴参考的经验和思路.The cuplock steel tubular scaffold is widely used in the construction of cast-in-situ bridges. By research into loading conditions, together with practical engineering, applied finite-element analysis software of MIDAS/Civil, we establish three-dimensional space model, calculate the carrying capacity, stability and capacity of foundation, providing technical help to the construction process and referenced designing and constructing experience of this kind of framework.

关 键 词：碗扣式钢管支架 计算模型 承载力 稳定性
