摘　　要：以四连体筒仓为例,对受损连体筒仓仓壁各类型加固方法的优缺点进行了分析,提出了体外预应力加固方案,并对体外预应力加固工艺进行了研究。工程应用表明,采用体外预应力技术可以大幅度减少穿过连接体钢筋数量,最大程度减小因加固开孔对筒仓连接部位的损害,加固效果较好,具有较好的推广应用价值。Taking the four connected silos as an example,the advantages and disadvantages of various types of reinforcement methods for the damaged connected silo wall are analyzed,the external prestressing reinforcement scheme is proposed,and the external prestressing reinforcement technology is studied.The engineering application shows that the external prestressing technology can greatly reduce the number of reinforcements passing through the connector and minimize the damage to the silo connection due to the reinforcement of openings.The reinforcement effect is good,which has good popularization and application value.
