摘要
乌龙江特大桥位于Ⅶ度地震区,主桥采用(80+3×144+80)m长联大跨混凝土连续梁结构,位于线间距变化段和曲线上。介绍大桥的结构设计、曲线上连续梁支座类型的选择和减隔震措施。
Wulong River Bridge is located at the seismic zone of Intensity VII. The main gird- er for the main bridge of the Bridge was designed as a long span and long continuous unit concrete continuous girder structure with span arrangement （80＋3×144＋80）m and the structure was arranged on the changed spacing distance and curved section of the railway lines. In this paper, the structural design of the Bridge is described, in which the selection of bearing types and the measures of seismic mitigation and isolation for the structure on the curved section are included.
