Abstract： The latest Technical code for engineering of ground anchorages and shotcrete support (GB 50086—2015) has made up the shortage of clear design standard of anti-floating anchor. By comparison with two other design documents commonly used before, the influence and variation rule in calculating the cross-sectional area of anchor tendon and anchorage length were pointed out, which can be as a reference for engineering colleagues.

Keywords： anti-floating anchor; cross-sectional area of anchor tendon; anchorage length
