摘要
以连霍高速拓宽工程中某T梁为例,利用ANSYS软件建立拓宽后T梁的空间有限元模型,研究在汽车荷载作用下不同连接方式对拓宽后桥梁结构的影响,提出新旧桥间不设置横隔板时桥梁整体和局部受力最为不利,建议采用新旧桥之间设横隔板而墩顶可不设置横隔板的横向连接形式。
In this paper,the T beam bridge in Lianyungang-Korgas Expressway is chosen as an example.The widening of entity model T spaces is built by ANSYS.The aim is to study the influence of different connections on the widening of the bridge structure.It is proposed that new and old bridge don＇t set the across partitions,which is bad in the bridges overall and local force.It advices adopting a horizontal connection form that setting tranverse diaphragms between new and old bridges,not on the top of piers.
