摘　　要：以高达333 m的深圳城建大厦项目为例,介绍了塔楼67~72层鱼腹式组合桁架结构的安装方法,通过方案比选、地面拼装、吊装工况的分析对塔冠鱼腹式组合桁架结构的安装进行了深入研究,采用“地面拼装、高空散拼、双机配合”的施工工艺,结合midas Gen等有限元软件分析、分段分节优化等一系列措施,可精确实现鱼腹式组合桁架结构的安装作业,保证施工的安全性,为类似项目施工提供借鉴。Taking the project of Shenzhen Chengjian Tower with a height of 333 m as an example,this paper introduces the installation method of 67-72F fish-belly composite truss structure of the tower crown.Through comparison and selection of schemes,ground assembly and analysis of hoisting conditions,the paper conducts an indepth study on the installation of fish-belly composite truss structure of the tower crown,and adopts the construction technology of"ground assembly,high altitude disassembly and double machine coordination".Combined with a series of measures such as midas gen and other finite element software analysis,segmentation optimization and so on,the installation operation of fish-belly composite truss structure can be accurately realized,ensuring the safety of construction and providing reference for similar projects.
