摘　　要：本文以中国沈阳茂业中心工程为例,介绍大型施工设备(内爬式STT553A塔吊)的拆除方案比选和在拆除施工过程中与超高层屋面结构的相互彩响分析。并对大型施工设备的拆除方案确定、结构计算和加固、施工过程控制等几方面进行阐述。在实际施工中,顺利完成了各项操作,并取得了良好的社会效益和经济效益,为以后的类似工程的施工提供参考。This paper takes the Shenyang Maoye Center Project in China as an example to introduce the analysis of the demolition scheme of large-scale construction equipment (internal climbing STT553A tower crane) and the interaction between the super-high-rise roof structure during the demolition construction process. It also elaborates on the demolition plan determination, structural calculation and reinforcement, and construction process control of large construction equipment. In the actual construction, the various operations were successfully completed, and good social and economic benefits were obtained, which provided reference for the construction of similar projects in the future.
