摘　　要：哈西大桥采用双塔双索面斜拉桥,跨径布置为(118+198+118)m,全飘浮体系,预应力混凝土结构。本文以哈西大桥主塔转体承台结构为研究背景,Midas/Civil 2019专用桥梁分析软件建立转体承台的有限元实体单元分析模型,按现行规范要求对转体承台结构进行了全面的计算分析。计算后转体承台结构各项受力性能均未超过限值,满足规范要求,可为今后此类转体桥梁的设计提供参考。The Haxi bridge is a twin tower double cable plane cable-stayed bridge,The span arrangement is(118+198+118)m,take the use of ull floating system and prestressed concrete structure.The paper based on the HaXi bridge's swivel bearing platform structure,using Midas/Civil 2019 bridge analysis software to make a model based on finite element solid element of swivel bearing platform,and this software has carried out the comprehensive design and analysis to the swivel bearing platform structure.Conclusion after calculation,all mechanical properties do not exceed the limit,which satisfy the standard requirement.Above all,this paper can provide reference for the design of this kind of swivel bridge in the future.
