摘　　要：为了研究横向预应力张拉技术在工程加固中的应用,通过在某住宅T形板加固工程的应用,研究了对被加固结构采用横向张拉施加预应力的原理,以及实现加固目标的施工工艺和质量控制方法。研究与实践表明,采用横向张拉预应力加固技术,锚固和节点处理简单,设备要求低,施工方法简便;便于在加固现场的应用,特别适用于一些中小构件的加固。加固后结构能够满足安全性和耐久性要求,效果良好。To study the vertical tension prestressing reinforcement in engineering applications, through the practical application of reinforcement in a T-shaped slabs, the research focuses on the principles of the verti- cal tension prestressing, and the construction technology and quality control methods of achieving the goals of reinforcement. Research and practice shows that the vertical prestressing reinforcement technology has its ad- vantages of simpler anchor and node, less equipment requirements and more convenient construction methods, easier to apply in the spot of reinforcement, especially for some small or medium member of the reinforcement; reinforced structure can meet the requirements of safety and durability with the good effect.
