摘要
针对上部为双薄壁墩下部为变截面独墩的组合型桥墩构造形式,结合贵州天桥特大桥工程实例,利用有限元ANSYS结构分析软件根据3种荷载工况组合,分析了双薄壁墩与独墩不同构造比例下对桥墩整体稳定性的影响。从桥墩稳定性分析,结果表明:双薄壁墩和变截面独墩墩高比例在0.5～1.0范围内较优。
The rational structure form of double thin-wall piers combined with variable cross section single pier was studied.According to combination of three load cases,the finite element software ANSYS was adopted to analyze pier's integral stability under different structural proportion of double thin-wall piers and single pier.The analysis results indicate that the height proportion of double thin-wall piers and single pier ranged from 0.5 to 1 is better.
