摘　　要：结合城市高架高独柱墩顶部发生横向位移这一现象,对高独柱墩顶部横向荷载产生的原因进行初步分析,并应用三维非线性屈曲分析,阐述组合荷载所引起的大变形及混凝土徐变效应与墩顶横向位移之间的关系,提出了设计、施工类似结构时应注意的事项。In combination with the phenomena of transverse displacement occurred at top of high single column pier of urban elevated bridge, the paper analyzes preliminarily the cause of transverse loading at the top of high single column pier and analyzes by three-dimensional non-linear yielding curved analysis. It also states the large deformation caused by combined load and the relation between concrete creep effect and transverse displacement at pier top. At the same time, it puts forward the matters needing attention when designing and constructing the similar structures.
