摘　　要：整体式桥台无缝桥梁是将桥梁的上部结构与桥台结为整体,避免了伸缩缝桥梁常见的水侵蚀和冻害。分析了桥梁伸缩缝装置存在的问题;介绍了国内外无伸缩缝桥梁的工程实践;提出了整体式桥台无缝桥梁应用中存在的问题。The jointless bridge with the integral abutment integrates the superstructure and the abutment into one mass, and thus avoids the water erosion and frost damage which usually happen to bridges with joints. Problems aroused by the expansion joint are analyzed and the engineering practices in jointless bridges home and abroad are introduced, including points for attention in popularizing that type of bridge.
