Abstract

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.
