摘　　要：悬臂挂篮施工是桥梁施工中一种应用广泛的施工工艺,结合某高铁桥梁工程实例,采用MIDAS软件对三角形挂篮和菱形挂篮进行内力和变形分析,得出该桥采用三角形挂篮更为合理的结论。实际工程中,应综合考虑多方面因素进行比选,得出最优方案。The construction of cantilever hanging basket is a widely-used construction technology in bridge construction.Combining with a high-speed railway bridge project,the internal force and deformation of triangular and rhombic hanging baskets are analyzed by MIDAS software,and the conclusion that triangular hanging basket is more suitable for this bridge is drawn.In practical engineering,many factors should be considered comprehensively to select the optimal scheme.
