摘　　要：灌河特大桥的斜拉索在主梁上的锚固采用锚拉板构造,锚拉板处荷载大,构造复杂,采用焊接连接,疲劳问题较为突出,通过足尺模型试验对这种新型锚固构造进行抗疲劳试验研究。The anchor plate structure was used for anchoring the stay cables of Guanhe River Bridge at its main girder level.The fatigue problem of the anchor plate is significant because the load at the plate is great,the plate structure is complicated and the plate is welded to the main girder.The fatigue resistance of such new type of the anchor plate structure is studied through full-scale model test.

关 键 词：锚拉板 模型 疲劳试验
