摘　　要：鉴于整体式桥台桥梁的受力性能复杂,目前的设计方法基本上是依赖于经验,文章以福建省永春县上坂大桥(我国目前修建桥长最长的整体式桥台桥梁)为工程背景,在实桥静载试验的基础上,采用有限元分析软件-ANSYS建立全桥的空间模型,分析了桥台刚度对该类桥梁受力性能的影响,在此基础上提出可供整体式桥台桥梁工程设计参考和建造的若干结论。Shangban bridge is the most long integral abutment bridge in China, which located in Yongchun county, Fujian province. Since the design of integral abutment bridge are basically depended on experience. In this paper, the three dimensional FEM model of integral abutment bridge is built with software- ANSYS, and the behavior of integral abutment bridge with different stiffness of abutment are analyzed, based on Shangban bridge and its field static test. Through analysis, some reference conclusion for the design and construction of integral abutment bridges are bring forward.
