摘　　要：描述了中国、美国、英国、日本等国的岩土锚杆标准中关于锚杆设计安全系数、验收试验及锚杆合格条件规定的合理性和必要性。揭示并分析了当前中国的某些岩土锚固工程安全系数偏小,缺少基本实验及降低验收试验标准所造成的严重危害。提出在锚杆验收试验中若出现不合格锚杆应增加验收试验锚杆数量,同时还对不合格锚杆承载力的可利用度判别及如何增补锚杆提出了意见和方法。这些工作都对提高岩土锚固工程的安全性起到重要作用。The rationality and necessity of specification for safety factor,acceptance test and qualification of anchor in the ground anchorage standards of China,America,British and Japan are discussed.At the same time,the endangerment of situation,such as depressing safety factor,reducing basic test and lowering standard of acceptance test in current China ground anchorage engineering is analyzed.Based on these discussions,it is presented if there are disqualified anchors in ground anchorage engineering,the number of acceptance test shall be increased.Moreover,the method how to estimate the utilizing of disqualified anchors and complement new anchors is given.Therefore,the achieved results can provide references to advancing the safety of ground anchorage engineering.
