| Abstract: | According to the design of the pier of Shenjiahe Super Large Bridge in Baotou-Xi＇ an railway, this paper introduces the calculation of dual-column pier structure and parameter optimization. The paper uses space finite element analysis model to calculate the natural vibration characteristics of the bridge. Using the theory of vehicle-bridge system coupling vibration, the paper assesses the dynamic performance of the bridge and the safety and the running comfort, providing refer- ence for similar projects. |
