| 摘 要： | 为研究单桩和带承台单桩承载性能的差异,对单桩和带承台单桩进行了静载试验对比,试验结果表明,在刚性承台的作用下,带承台单桩桩身上部轴力的衰减较慢,产生了侧阻的削弱效应,摩阻力-位移关系曲线出现软化现象,但桩端阻力的发挥得到了增强;在相同桩顶荷载下,带承台单桩中桩顶的沉降量较单桩的桩顶沉降量大。

| Abstract: | The static load tests of single pile and single pile with cap are conducted,the results show that the rigid cap makes the axial force decrease slowly,cut the frictional resistance and soften the transfer function at the upper pile,but makes the end-bearing increase.At the same load on the top of pile,the displacement on the top of the single pile with cap is larger than the one of the sigle pile. |
