摘　　要：介绍了国内外对锚栓抗拉性能的研究成果,锚栓受拉破坏模式有五种形式,其中混凝土锥体破坏是最常见的。分析了影响锚栓受拉承载力的因素,并对两种锚栓受拉承载力计算公式进行了对比分析,最后对今后研究方向提出了建议。Research achievements of tension behavior of anchors in conctrete at home and abroad are presented. Five failure modes of anchors subjected to tension loads may occur. Among these failure modes, concrete breakout failure is the most common. Factors affecting the tension-resistance bearing capacity of anchors are discussed. Also contrast analysis on formulae used for computation of tension-resistance bearing capacity of anchors is conducted. At last some advices are given for further research.
