摘要
以高速客运专线铁路上跨度(60+128+60)m连续梁拱桥为研究对象,采用空间有限元分析模型,计算桥梁的自振特性,探讨横撑刚度和拱肋截面形式对桥梁自振特性的影响,评价桥梁的动力性能和列车运行安全性与舒适性。
Taking a continuous beam and arch bridge with spans （60＋128＋60） m on highspeed passenger dedicated railway as the research object, this paper calculates natural vibration property of the type of the bridge by means of spatial finite element analysis model, makes a study of influences of the cross strut stiffness and arch rib cross section types on the vibration property and also evaluates various dynamic properties of the bridge, train traveling safety and passenger comfort.
