为明确“平接头+快速连接件”新型管片环缝抗剪性能，设计不同纵向力工况下的环缝抗剪室内试验，通过对环缝剪切试验现象及荷载-错台曲线分析该新型环缝抗剪机制，得到不同纵向力对环缝抗剪的影响规律、同阶段环缝抗剪刚度及环缝承载力。主要结论如下： 1）相比传统“平接头+斜螺栓/弯螺栓”环缝，该类型环缝在发生错台时，快速连接件可及时发挥抗剪作用，能有效抑制环缝错台； 2）由于环缝弹性阶段抗剪刚度远大于塑性阶段，在隧道施工运营过程中，为保证文中尺寸的快速连接件管片环缝的抗剪性能，可将错台量控制在5.51 mm内。

To explore the shear resistance of the "flat joint + quick connector" type segment circumferential joints, indoor tests are designed on shear resistance of segment circumferential joints under various longitudinal forces. The shear resistance mechanism of such segment circumferential joints are analyzes via test results and loaddislocation curves, obtaining the influence patterns of longitudinal force on the shear resistance of circumferential joints and the shear stiffness and the bearing capacity of the circumferential joints at the same stage. Conclusions are drawan as follows: (1) The quick connectors of the recommended circumferential joints can effectively control the dislocations, which is superior to convational "flat joint + nclined/curved bolt" type segment circumferential joints. (2) The shear resisitance of circumferential joints is far lager in elastic stage than plastic stage, thus it is recommended to control the dislocation within 5.51 mm to guarantee the resistance of circumferential joints.
