摘　　要：通过对桥梁工程中使用预应力自动化张拉技术工艺阐述,同时与传统工艺进行对比分析,指出自动化张拉工艺通过数字化控制,不但提高了施工精度,减少了因张拉精度失控造成的预应力工程事故,同时增大桥梁结构的合格率。The paper illustrates the prestressed automatic tension technique applied at bridge projects, undertakes the comparative analysis of the technique with the traditional craft, points out the construction accuracy can be improved, the prestressed project accidents caused by the runaway of the tension accuracy by the digital control of the automatic tension craft, and the qualified rate of the bridge structures can be enhanced.

关 键 词：桥梁工程 自动化张拉 应力损失 质量控制
