摘要
以某枢纽匝道变宽桥为例,采用有限元软件MIDAS/Civil进行梁格法分析,对该桥的梁格划分及截面特性的计算进行了详细说明,并对该桥的支座反力、位移进行了分析,得出该桥采用梁格法模拟的合理性,为以后同类型桥梁的设计提供了借鉴和参考。
Combined with a hub ramp broaden bridge as an example, this paper used the finite element software MIDAS/Civil for grillage method analysis, it explained detailed in the beam division and the calculation of the characteristics of the bridge section, it also analyzed the force of support, displacement of the bridge, it ob-tained its rationality of using the grillage method simulation, and provided reference for the future design of the same type bridges.
