摘要
以128 m钢管混凝土拱为研究对象,采用空间有限元分析模型分析计算桥梁的动力特性,探讨了横撑刚度和拱肋截面形式对桥梁动力特性的影响,提出桥梁的动力性能和列车运行安全性与舒适性,为今后此类桥梁的设计提供参考。
Taking the 128 m steel tube arch as the subject, the paper, using the space finite element analysis model, analyzes and calculates the dynamic characteristics of the bridge. It also explores the influence of the lateral brace and the arch lib section type on the dynamic characteristic of the bridge. It points out the power performance of the bridge as well as the safety and the riding comfort of the train. It is beneficial for the design of bridges of this type.
