摘　　要：介绍了屈服锚杆的工程应用背景和作用机理;综述了国内外近期研制的几种新型屈服锚杆结构、工作原理及其相关试验研究成果,包括国外的Garford锚杆、Yield-Lok锚杆、Roofex锚杆、新型吸能锚杆和D锚杆以及我国的CRLD锚杆和新型高强预应力让压锚杆;在此基础上分析了当前屈服锚杆研制中存在的问题,指出了屈服锚杆今后的研究方向。The engineering application background and action mechanics of yielding bolts are introduced. The structure, operating principles and relevant test research results of several new yielding bolts are described, including foreign Garford bolt, Yield-Lok bolt, Roofex bolt, new energy-absorbing bolt and D bolt, and Chinese CRLD bolt and new high-strength prestressing yielding bolt. The existing problems in the development of current yielding bolts are analyzed. The future research directions of yielding bots are pointed out.
