预应力技术在桥梁工程施工中的应用

预应力技术在当前的桥梁项目中应用广泛,是一种重要的施工技术,可以在减轻桥梁结构自重的基础上改善结构受力分布情况,进而增强桥梁结构稳定性,尤其适用于大跨度或复杂结构桥梁工程。文章简要探讨预应力技术的应用范围,并对技术的应用要点进行重点阐述。

The prestressed technology is widely used in the current bridge project, and it is an important construction technology.It can improve the stress distribution of the bridge structure on the basis of reducing the dead weight of the bridge structure, andthen enhance the stability of the bridge structure. It is especially suitable for long span or complex structure bridge engineering. Thispaper briefly discusses the application scope of the prestress technology, and expounds the key points of the application of the tech-nology.
