摘要
异形墩结构是近几年出现的新型桥梁结构,它的出现改善了墩身结构的受力性能,促进桥梁结构向着设计新颖、合理经济等方面发展,采用通用有限元程序ANSYS对西成客运专线椒溪河特大桥异形墩进行实体有限元分析,考虑恒载和活载的作用下,分析得到异形墩墩身应力分布状态,拓展了异形桥墩的使用范围,为实际的施工过程提供一定的指导建议。
Irregular pier structure is a new type of bridge structure emerging in recent years, which has improved the mechanical performance of the structure, and promoted the bridge structure towards novel design, reasonable and economic development. This paper uses the general finite element program ANSYS for the finite element analysis of the Jiaoxi River grand bridge irregular pier of Xicheng passenger dedicated line. Considering the action of dead load and live load, the stress distribution state of the irregular pier is analyzed, thus expanding the use of irregular pier, and providing certain guidance for the actual construction process.
