| 摘 要： | 运用多元线性回归分析理论，探讨了单桩承载力与静力触探成果之间的相关关系；结合土层和桩本身的特点，建立了单桩承载力研究的多元线性回归分析数学模型；通过实例验证，说明其具有一定实用价值，适合于地区性单桩承载力的研究，探索出地区性单桩承载力的经验公式。本文研究结果适用于徐州地区沉管灌注桩。对比结果表明，回归分析结果优于规范计算结果。

| Abstract: | The correlation between the pile bearing capacity and Cone Penetration Test (CPT) results is studied by means of multiple regression analysis. The mathematical model of multiple regression analysis of pile bearing capacity is established, and its practical value is proved by a case study. The present method is suitable for the study of local pile bearing capacity, and a relevant empirical formula can be obtained. The result obtained in the paper is suitable to Xuzhou region, and is better than that of regular calculation. |
