| Abstract: | 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. |
