中文摘要：

大跨空间预应力钢结构形式多样，力学特性差异大，相应的施工分析和施工方法等差异也很大。本文结合张弦结构、斜拉结构、弦支穹顶和索穹顶等典型结构形式，介绍了各种结构形式的主要施工技术。井以索穹顶结构为例，介绍了张力结构的创新施工技术和创新施工分析方法。通过大量工程实践，埘这些技术不断总结、提高和完善，集成了大跨空间钢结构预应力施工成套技术。

英文摘要：

Long-span space prestressed steel structure has various forms and its mechanical properties, construction analysis and construction technology are different. Based on typical structure forms such as beam string structure, cable-stayed structure, suspend-dome and cable dome structure, main construction technologies are introduced. According to cable dome structure, innovation technology and analysis method are introduced. Based on engineering practices, packaged technology of prestress construction tbr long-span space steel structures are integrated by summarizing and improving these technologies.
