摘　　要：目前轨道交通装备、铁路桥梁、钢结构站房建筑等节点连接主要有焊接、螺栓连接、环槽铆钉连接三种连接方案,其中焊接、螺栓连接已大规模应用数百年,相关的研究内容已趋于完善。但环槽铆钉连接为新型连接型式,国内相关研究较少,本文就不同孔径、孔型对环槽铆钉预紧力力学性能的影响开展了研究,为各领域技术人员使用环槽铆钉产品提供技术参考。At present,there are three main connection schemes for nodes such as rail transit equipment,railway bridges,and steel structure station buildings:welding,bolt connection,and ring groove rivet connection.Among them,welding and bolt connection have been widely used for hundreds of years,and related research content has become more perfect.However,the ring groove rivet connection is a new type of connection,and there is relatively little research in China.This article conducts research on the influence of different aperture and hole types on the clamping force and mechanical properties of ring groove rivets,providing technical reference for technical personnel in various fields to use ring groove rivet products.

关 键 词：孔径 孔型 预紧力 环槽铆钉连接技术
