摘　　要：体外预应力越来越广泛地用到历史保护建筑的加固中,而传统的张拉工艺在张拉精度、伸长值测量、同步精度等方面却常常达不到设计要求。预应力智能张拉技术通过计算机将预应力张拉过程自动化,并能实施自动采集数据,将预应力张拉工序可视化,可以达到预期的效果。以具体工程为背景,详细介绍了该技术的应用。The external prestress becomes more and more widely-used in the historic and protected building reinforcement, while in the respects of tensioning precision, elongation value measurement and synchronization precision, the traditional tensioning technology usually cannot meet the design requirements. Through the computer, the intelligent prestressed tensioning technology can make such process automatic, can have the data automatically collected, and the prestressed tensioning process visualized, and can achieve the desired results accordingly. Taking a specific engineering as an example, a detailed application of such technology has been introduced in this paper.
