| 摘 要： | 本文采用通用有限元软件建立拱桥结构模型，在尖湖钢管混凝土拱桥施工监控的基础上，对成桥阶段的拱肋进行受力分析计算，并与实际检测数据进行对比，相关性良好。比较结果表明，采用此模型可以基本上模拟钢管混凝土拱桥的实际受力状态，并可为施工监控提供理论支持。

| Abstract: | Based on the study of Jianhu CFST arch bridge, a 3-D finite element model was established with current software of FEM, and the forces acted on the arch rib were analyzed. The results indicate that the gauged stresses are consistent with the theoretical counterpart. As a result, this model can simulate the practical status of the bridge, and can also offer a theoretical aid in monitoring and controlling bridge construction. |
