摘　　要：采用Ｓｕｐｅｒ－ＳＡＰ程序的块体单元，对广州内环线展翅梁结构进行了节段三维应力场分析，得出了各工况控制应力，发现了常规分析计算的不足，优化了截面尺寸，为展翅梁结构的细部构造及结构设计提供了可靠的依据。By using brick element of Super SAP program,a three dimension stress of wing structure in Guangzhou internal ring was analyzed.The controlled stresses on various behaviour and potimization dimen sions of section were obtained,and the defects in the routine analysis were founded.It was provided a reliable basis for structure design.
