摘　　要：本文介绍南京长江第二大桥南汊主桥流线形扁平薄壁钢箱梁横隔板的空间节段模型和采用梯形纵向加劲肋钢桥面计算的等效格子梁法,分析了正交异性板的第二体系的应力,和传统的Peklian Esslinger法相比较,采用空间节段模型和等效格子梁法得到的结果更加全面、准确。In this paper,the spatial phase model of thin wall streamline flat box girde's traverse plate and equivalent girder beam are introduced into the analysis of orthotropic steel plate with trapezoidal longtitudial rib and the second system stress of orthotrpic plate.Compared with PeklianEsslinger traditiona method the results of stress analysis got by spatial phase model and Equivalent girder beam mehtod are more precise and complete.
