摘　　要：在旧桥维修加固中,对弯坡斜桥上的多跨连续曲线钢筋混凝土箱梁位移后的纠偏加固,是一大难点。通过对天津十一经路立交桥连续曲线钢筋混凝土箱梁的纠偏加固设计,为此类工程提供了实践经验。In the maintenance and stabilization of old bridges, the deviation rectifying and stabilizing for multi-span block curved reinforced concrete box girder of skew bridge on slope after displacement is a big problem. The design of deviation rectifying and stabilizing on block curved reinforced concrete box girders of Shi-Yi-Jing Rd Grade Separation in Tianjin provides practical experiences for constructions of this kind.
