| 摘 要： | 通过南京三江口旋挖钻孔灌注桩静载荷试验与轴力测试,分析了旋挖钻孔灌注桩的荷载传递机理和承载特性。研究结果表明,试桩为摩擦型桩,其竖向承载力主要由桩侧摩阻力提供,且侧摩阻力明显大于按桩基规范所确定的数值。同时,对试桩的抗拔力和水平承载能力进行了测试。 |
| 关 键 词： | 旋挖钻孔灌注桩 荷载传递 现场试验 软弱土地基 |

| Abstract: | Based on the results of vertical loading test and stress test for the churning driven cast-in-place piles in Sanjiangkou Nanjing, the load transfer mechanism and vertical load bearing behavior of the pile are discussed. The analysis shows that the tested piles behave as friction piles, with the vertical bearing capacity being supplied mainly by side friction resistance. The side friction resistance is higher than that by survey reports obviously. Horizontal loading capacity and lift loading capacity are tested in the paper too. |
