摘　　要：随着经济和社会的发展,城市桥梁建设对造型美观及节约用地的要求不断增高,高架桥双支座独柱花瓶墩应用也日益增多.由于以往设计的花瓶墩出现了一定的墩顶开裂情况,现结合成都地区某高架桥工程,利用实体有限元模型分析结果与常用的简单计算模型计算结果进行对比分析,检验各种常用简单计算模型的合理性,为以后类似桥墩的设计提供必要的经验借鉴.With the development of the economy and society,the requirements for beautiful appearance and land conservation in urban bridge construction are constantly increasing.The application of double-support single-column vase pier in elevated bridges is increasing,and at the same time,the previous designs of vase piers have shown some cracking at the top of the piers.Combined with an elevated bridge project in Chengdu,the analysis result of a solid finite element model is compared and analyzed with the results of common simple calculation models to verify the rationality of each common simple calculation model,which provides the necessary experience and reference for the design of similar bridge piers in the future.
