| 摘要: |
| 测试了相同规格刚芯水泥土搅拌桩和混凝土钻孔灌注桩的承载力，并研究了芯桩长度对刚芯水泥土搅拌桩承载力的影响。结果表明，刚芯水泥土搅拌桩的承载力是钻孔灌注桩的1.36～1.54倍，而价格仅为钻孔灌注桩的26％～31％；提高芯校长度比可提高单桩承载力，但长度比超过0.6后，承载力增长缓慢；相同长度的刚芯水泥土搅拌桩，芯桩越长，单桩承载力越高。 |

| Abstract: |
| The bearing capacity of the same specification cement soil mix stake and the concrete drill-holing stake,and the influence of staking length to the cement soil mix stake bearing capacity were tested.The result showed that,the bearing capacity of the cement soil mix stake is 1.36-1.54 times to drill-holding stake,but the price is only 26%-31% of drill-holding stake.Increasing the length ratio of stake can increase the bearing capacity of single stake,but it exceeds 0.6 empress,the bearing capacity increases slowly,but for the same length cement soil mix stake,the longer the stake is,the higher is the single stake bearing capacity. |
