摘　　要：根据上海地区的土锚抗拔试验结果,分析了在饱和软粘土中土锚轴向力、钢筋应力以及侧摩阻力沿土锚的分布规律,讨论了确定土锚极限承载力时应充分考虑钢筋、注浆体的强度问题,并提出了在类似上海的饱和软粘土中土锚的侧摩阻力的参考取值。On basis of the pull - out test results of the soil anchors in Shanghai area, the article analyzes on the distribution pattern of the axial forces, re-bar stresses and lateral frictional resistance of the soil anchors installed in the saturated soft clays, discusses on the strengths of the re-bars and grouting mortars that should be fully considered during the determination of the ultimate capacity of the soil anchors, and recommends a reference value for the lateral frictional resistance of the soil anchors in saturated soft clays similar to those in Shanghai area.

关 键 词：土锚 抗浮 极限承载力
