| 摘 要： | 在基坑中对等截面单桩进行了抗拔静载试验，在桩身设置应变式钢筋计，成功测得桩身各截面的应变数据。分析试验所得数据，对试验抗拔桩抗拔系数的取值、侧摩阻力的发挥、混凝土桩身的开裂等进行了探讨，相应给出了抗拔桩的设计建议。 |
| 关 键 词： | 基坑 抗拔桩 等截面单桩 抗拔承载力 侧摩阻力 长螺旋灌注桩 |

| Abstract: | Anti-lift static test was made on single pile with uniform cross section in foundation-pits. Strain type steel device was installed on the pile and the strain data on different section in pile were measured successfully. Discussion on value of anti-lift coefficient of test piles, development of lateral friction drag and cracking of concrete pile body were made. The design suggestions about anti-lift piles were given out. |
| Keywords: | foundation pits anti-lift piles single pile with uniform cross section anti-lift capacity lateral friction drag llong helix bored piles |
