摘　　要：针对东南沿海早期建造的石结构房屋以及许多古代石建筑承载能力普遍不足的情况,提出了对作为石结构重要受力构件的石梁进行加固的迫切性。分析了石梁自身的特点及对其加固设计时应注意的问题,详细阐述了3种不同的加固技术。同时,基于3种不同的加固技术,探讨了目前石梁加固存在的主要问题以及加固研究前景,对实际加固工程中合理选择加固方案具有一定的指导作用。In view Of the insufficient bearing capacity of stone houses built in the early stage in southeast coast and many ancient stone buildings, it＇ s particularly urgent to strengthen the stone beams which are the important structural components. The characteristics of the stone beams and the problems during the strengthening are analyzed. At the same time, three different strengthening technologies are presented in detail according to the existing data. Furthermore, the main existing problems at present when the beams are strengthened and the prospects of the related research are discussed based on the three different strengthening technologies, which has a guiding role to select a reasonable reinforcement scheme in the actual project.
