摘要
通过对包头西安铁路史家河特大桥桥墩的设计,对双柱门式墩结构的计算、参数优化等进行了介绍。采用空间有限元分析模型,计算了桥梁的自振特性。采用车桥耦合振动理论,评价了桥梁的动力性能和列车运行安全性与舒适性,为同类桥墩的设计提供参考。
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.
