摘　　要：针对目前我国跨度最大的球面钢网壳工程——河南省体育中心体育场273m跨钢网壳，安装所采用的高空散装法施工技术进行了全面介绍。同时对结构在施工过程中的杆件的内力变化进行了全过程跟踪，分析结果表明，这种方便的施工技术是可行的，结构在施工中是安全的。通过施工内力的分析，特别指出网壳工程施工时，应进行细致的施工内力分析。同时对确定网壳施工方案时应注意的一些问题提出了建议。Presented the construction technique of a double-layer spherical reticulated steel shell with a span of 273 m of the Stadium of Henna Sports Center, which is the largest spherical latticed shell in china to date. The high altitude bulk^loading erection method was adopted, where only simple construction tools were used in the installation of the huge reticulated shell. The variation of internal forces during the whole erection process is also analyzed. The results of the analysis indicate that the project is safe during the whole erection process. In the article, authors state that it is important to analyze the construction internal forces in the process of installation. Finally, some issues that need to be considered in determining the construction scheme of reticulated shells were indicated.
