摘　　要：随着国内高速公路的发展,互通范围内分叉口越来越多,因此变宽箱梁的分析越来越重要。结合云南昆明某高速公路工程,采用有限元软件MIDAS/Civil对变宽段异性梁进行了梁格法分析,并将分析结果与单梁结果进行了对比,证明了该桥采用梁格法模拟的合理性。分析结果可为以后同类型桥梁的设计提供参考。With the development of expressways in China, there are more and more road forks in the interconnected range. Therefore, the analysis of widening box girder is more and more important. Combined with an expressway project in Kunming of Yunnan, the finite element software MIDAS/Civil is used to carry out the grillage method analysis on the widening girder, and the result is compared and analyzed with the result of the single girder to reach the rationality of grillage method used in the simulation of this bridge. The analysis result can be referred for the design of the similar bridges in the future.
