| 摘 要： | 从径向土体固结方程出发,利用e-logσ和e-logk模型,推导出瞬时加载情况下,考虑应力集中、涂抹区影响和桩阻效应的复合地基固结解,分析结果表明:随着Cc/Ck的增大,复合地基固结速率减小,且Cc/Ck对固结的影响随桩阻变化很小;应力比对复合地基固结速率的影响较小。 |
| 关 键 词： | 复合地基 桩阻效应 固结速率 应力比 长细比 |

| Abstract: | Starting from horizontal soil consolidation equation,using e-logσ and e-logk model,the paper induces the composite foundation consolidation under the condition of considering instant load,stress concentration,trowelling zone impact and pile resistance effect.The analysis results show that: with the Cc/Ck increasing and composite foundation consolidation rate will reduce,the impact of Cc/Ck upon consolidation will be reducing with the pile resistance changing,the impact of stress ratio upon composite foundation consolidation rate is smaller. |
| Keywords: | composite foundation pile resistance effect consolidation rate stress ratio slenderness ratio |
