摘　　要：对先简支后连续桥梁上进行梁板运输作业的安全性进行了分析。根据某先简支后连续桥梁的设计参数建立了三维空间有限元模型,分析了在单跨20 m的空心板桥和单跨40 m的T梁桥上进行运梁作业时结构的内力,并对梁板间有无横向联系、运梁车跑偏等情况进行了具体分析对比。最后,根据计算分析的结果给出了合理建议。This article analyzes the safety of transporting girders on simple-supported continuous bridge.A three-dimensional finite element model was established based on the design parameters of a simple-supported continuous bridge.The internal forces of the structure during girders transportation operations were analyzed on a hollow slab bridge with a single span of 20 m and a T-beam bridge with a single span of 40 m.Specific analysis and comparison were made on whether there was a lateral connection between the beams and slabs,as well as the deviation of the beam transportation vehicle.Finally,reasonable suggestions were provided based on the results of the calculation and analysis.
