摘　　要：三角托架是桥梁施工过程中一种重要且应用广泛的临时支撑方式。采用MIDAS软件对三角托架的内力和变形进行分析计算,得到了三角托架在上部荷载作用下的内力和变形分布规律,为三角托架的设计和施工提供参考。Triangular bracket is an important and widely-used temporary support mode in bridge construction.The internal force and deformation of triangular bracket are analyzed and calculated by using MIDAS software.The distribution laws of internal force and deformation of triangular bracket under the upper load are obtained,so as to provide reference for the design and construction of triangular bracket.

关 键 词：特大桥 三角托架 内力 变形
