| 摘 要： | 完成了一组水泥土搅拌桩4桩复合地基载荷试验及桩顶应力、桩间土反力的原位测试。试验结果表 明,复合地基承载力高于单桩承载力;桩体屈服前,复合地基桩土应力比、桩土分担荷载比、应力集中系数、桩 间土承载力折减系数随外加荷载的增加而增加;应力减少系数随外荷载的增加而减小。

| Abstract: | The results of vertical static loading test and in-situ tests of composite foundation with four cement-soil piles are introduced.The stress ratio between pile and soil,the load partaking ratio between piles and soil,the concentration coefficient of pile stress,the reducing coefficient of bearing capacity of composite foundation increase,and the reducing coefficient of soil stress decreases in the process of loading. |

| Keywords: | cement-soil pile composite foundation stress ratio bearing capacity reducing coefficient modulus |
