等截面单桩抗拔承载性状试验研究

Test and Research on Anti-lift Properties of Single Pile with Uniform Cross Section/

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。

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.
