| 摘 要： | 夯实水泥土桩承载力的确定是夯实水泥土桩复合地基设计中的最关键问题，通过理论推演和简化分析，结合工程实践找到了夯实水泥土桩侧摩阻力和桩侧土层天然地基承载力标准值之间的理论关系。夯实水泥土桩单桩极限承载力标准值除以分项系数为单桩（容许）承载力标准值，通过上部结构荷载分项系数分析，得出结论，单桩承载力分析系数应采用1.65而不宜再采用2.0。 |
| 关 键 词： | 夯实水泥土桩 摩阻力 单桩 承载力 复合地基 |

| Abstract: | Determination of load-bearing capacity of punning cement-soil pile is the most important question in the design of punning cement-soil pile. Through theoretical calculation, simple analysis, and engineering practice, the theoretical relation is found between pile side friction resistance of punning cement-soil pile and standard value of natural foundation load-bearing capacity in the soil layer of pile side. The standard value of limited load-bearing capacity for a single pile of punning cement-soil pile divided by partition coefficient is the standard value of load-bearing capacity for a single pile (allowable). By analysis of partition coefficient of top load, it comes to a conclusion that partition coefficient of load-bearing capacity for a single pile should be 65, not 2.0. |
| Keywords: | punning cement-soil pile friction resistance of pile side partition coefficient of load-bearing capacity for a single pile |
