摘　　要：在对漳州九龙江大桥三角钢构区域的应力分析研究中,采用三维光弹性实验与有限元相结合的方法,得到两种典型工况下的应力大小及分布情况。最后,根据节点的应力集中程度以及局部应力分布规律,在设计上提出建议以改善其安全性和合理性。Three dimension photo - elastic experiment combining finite element is employed to investigate the distribution of tress oll triangular frame of Jiulong River Bridge. The regularity of local stress distribution and the degree of stress concentration on the two typical working conditions are studied. Finally, advice on designs is proposed to improve security and rationality on the basis of the degree of the tress concentrating on the consolidation zone and the law of local tress distributions.
