客运专线提篮拱桥动力性能分析

摘要

Handle-basket arch bridge not only possesses spatial aesthetic feeling,but also has good spatial property, it can improve the bridge's dynamic stability property. The 112 m span handle-basket arch bridge is take for example, used the finite element software to build model, analyzed the natural frequency of the bridge, and the change of the steel pipe's diameter, wall thickness's influence to the structure's natural frequency.%提篮拱桥不但具有空间的美感,并且具有良好的空间性能,能够提高其动力稳定性能.以112 m提篮拱桥为例,运用有限元软件建立模型,分析提篮拱桥的自振频率.钢管的直径的改变、钢管壁厚的改变对结构自振频率的影响.
