摘　　要：为加快黄冈大桥全桥南跨引桥预制T梁的施工进度,采取通过北侧梁板运输车过桥运梁支援南侧的T梁施工方案。通过有限元结构分析软件建模,对梁板运输车在钢箱梁结构不同工况下的应力和变形进行计算,对结果进行分析,表明在不同工况荷载作用下,钢箱梁段不同结构部位产生的应力和变形满足设计要求,说明该方案的可行性。In order to speed up the progress of construction of Huanggang yangtze bridge,the meas-ures of transporting precast T beam from the north side with plate transport vehicle crossing bridge girder to support the south side T beam construction are performed.Through the finite element analy-sis software modeling,the stress and deformation of beam transport vehicle under different conditions of steel box girder structure is calculated,and the results show that the stress and deformation of steel box girder sections in different structure parts under different load cases can meet the design require-ments,which has proved the feasibility of this scheme.
