预应力施工技术在大偏坡桥梁工程中的应用

Application of Prestressing Construction Technology in Bridge Engineering with Large Slope

以贵州双龙航空港经济区双龙北线道路工程中的大偏坡桥梁作为研究案例,探讨预应力施工技术在桥梁工程中的具体应用。研究结果表明:工程经预应力施工技术施工后,取得了较为理想的施工效果。预应力施工技术能够有效提高工程的强度性能,避免竣工后的桥梁开裂问题。

Taking the large slope bridge engineering in the north route of Shuanglong Airport Economic Zone in Guizhou as a case study,the concrete application of prestressing construction technology in bridge engineering was discussed in this paper.The research results show that after the project is constructed by prestressing construction technology,the ideal construction effect has been achieved.The prestressing construction technology can effectively improve the strength performance of the project and avoid bridge cracking,which is worth promoting.
