摘　　要：借助于有限元软件ABAQUS对桩柱式桥台进行非线性接触的三维有限元分析,模拟研究其在不同荷载组合下的应力及变形。结果表明:台后车辆荷载对背墙的应力和变形影响很小,设计时可不考虑;盖梁设计时所有荷载都应考虑;主拉应力与主压应力所在区域应适当增强。籍此,有望为桩柱式桥台的设计提供帮助。Three-dimension finite element analysis of non-linear contact is conducted to pile pillar abutment by general finite element program ABAQUS,stress and displacement simulation analysis of pile pillar abutment with different load combinations. The results show that the vehicle load has little impact on stress and displacement of parados,and it can be not considered; all of the load should be considered when designing cap beam; the min principal and max principal region should be strengthened. Based on this,it is expected to provide help for the design of pile pillar abutment.
