摘　　要：采用钢套筒挤压方案,研制了一种套筒挤压式屈服锚索,对屈服锚索屈服装置的"荷载-变形特征"进行试验研究,分析探讨了套筒挤压长度与屈服荷载的关系。试验结果显示,各组试验锚索初始屈服荷载和平均屈服荷载特征曲线比较一致,说明该锚索屈服装置方案合理、性能稳定,能够获得屈服锚索预期的屈服荷载和屈服长度。Applying steel sleeve extrusion project, an extrusion sleeve type yield anchored cable was developed. By “load-deforma-tion” test of yield device, the relationship between sleeve extrusion length and yield load was analyzed. Results showed that the first yield load and average yield load characteristic curves of every group samples were similar, which indicated that the yield device’ s performance was stable and could obtain expectant yield load and yield length of yield anchored cable.
