摘要
通过对已服役27年某中承式钢管混凝土组合拱桥采用刚度增大法进行加固10年后的荷载试验研究,并结合有限元方法分析对比了该中承式钢管混凝土组合拱桥加固前后的计算结果,从而得出刚度增大法加固效果良好的结论。
In this paper,the load test research on a CFST composite arch bridge in use for 27 years which was reinforced by increasing its rigidity ten years ago is performed.The results before and after reinforcement of the half-through CFST composite arch bridge which were computed and analyzed by finite element method are compared.The conclusion that the reinforcement effect by adding stiffening steel longitudinal beams is good is obtained.The reference for the similar strengthening method may be provided later.
