摘　　要：哈大客运专线双线铁路新开河大桥为1孔138 m下承式钢箱系杆拱桥,拱脚设计及受力情况复杂,着重介绍该桥拱脚的结构设计,并利用大型有限元程序ANSYS进行应力分析。The double-track Xinkai River Bridge on Harbin-Dalian Passenger Dedicated Rail- way is a through steel box tied arch bridge with a single span of 138 m and the design and force conditions of the arch springs of the Bridge are complicated. This paper mainly presents the structural design of the arch springs and analyzes the local stress of the springs, using the large finite element program ANSYS.

关 键 词：系杆拱桥 钢箱 拱脚 有限元分析 应力分析
