摘　　要：环向预应力加固技术是一种有效的结构加固方法,通过在结构周围施加预应力,能够提高结构的承载能力和抗震性能。本综述对环向预应力加固技术的研究现状进行了总结和分析,通过对国内外相关文献的调研,总结了目前环向预应力加固技术的不同类型结构中的应用案例,并对其效果进行了评估。并对加固过程中出现的预应力损失进行了总结分析。最后,针对目前存在的问题和不足提出了未来研究的方向和发展趋势,为该领域的研究和应用提供参考。The technique of circumferential prestressing is an effective method of structural strengthening. By applying prestress around the structure, the bearing capacity and seismic performance of the structure can be improved. This review summarizes and analyzes the current research status of circumferential prestress reinforcement technology, and summarizes the current application cases of circumferential prestress reinforcement technology in different types of structures through the investigation of relevant literature at home and abroad, and evaluates its effects. Finally, according to the existing problems and shortcomings, the future research direction and development trend are put forward to provide reference for the research and application in this field.
