本文应用ＳＡＰ５程序中的第八类厚壳单元，对南昆铁路八渡南盘江特大桥Ｖ形支撑局部结构模型进行了应力分析，绘出了各部位等应力迹线，并揭示出了常规内力分析中不能发现的一些问题，为合理确定Ｖ形支撑局部构造及结构设计提供了可靠的依据
In this paper, the eighth kind of thick shell element in SAP5 program is applied to stress analysis of the local structure model of V-shaped support of Nanpan-Kunming-Nanchong River Bridge of Nan-Kun Railway. The isokinetic stress trace of each part is plotted, Some problems that can not be found in the internal force analysis provide a reliable basis for the reasonable determination of the local structure and structural design of the V-shaped brace
