摘　　要：结合润扬大桥世业洲互通匝道的实际工程 ,针对不同构造形式的弯梁桥 ,浅析了弯梁桥发生爬移问题的机理 ,着重介绍了一些预防爬移问题出现的处理措施 ,即侧向限位设计 。In recent years, some curved girder bridge's diseases and accidents have been reported. Our engineers have paid attention to these problems and begin to solve the problem. In this paper, the design of lateral displacement resistance of curved box girder bridges in Shiyezhou interchange of Runyang Yangtze River Highway Bridge has been introduced. According to different structure forms of curved girder bridges, to prevent the damage to curved bridges when they are working.

关 键 词：弯梁桥 支座 侧向位移 限位设计
