［摘要］最新的《岩土锚杆与喷射混凝土支护工程技术规范》（GB 50086—2015）弥补了在此之前抗浮锚杆设计无相应明确行业标准的不足。本文经与以前常参照设计的两本文献比较，指出了新规范在计算杆体截面积和锚杆锚固长度方面的影响和变化规律，供同行参考。

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
