摘　　要：对某大桥正交异性钢桥面板的纵肋—面板焊接接头进行了热点应力法实体单元有限元分析,通过ABAQUS的模拟分析结果表明,轮压对于正交异性板钢桥面板的应力影响范围很小,对纵肋—面板焊接接头的应力提升不明显,接头非线性应力分布在距离焊趾0.4t的范围内,应力分布特点与以往针对平板焊接结构的热点应力研究成果相吻合。The paper carries out the finite element analysis of hot-spot stress method of orthotropic longitudinal rib-surfacing plate welding joint.ABAQUS simulation results show that： the wheel-pressure has little effect upon the steel-plate bridge stress influence scope of orthotropic plate,there is little effect of longitudinal rib-surfacing plate stress,nonlinear stress distribution of the joint is within 0.4t,stress distribution features are in accordance with the hot-spot stress research achievements of the horizontal plate welding structure.
