福州地区静力触探与旁压试验地基承载力计算对比研究

Comparative study on calculation of foundation bearing capacity of static penetration test and lateral compression tes in Fuzhou area

依托福州市在建轨道交通工程勘察项目进行静力触探试验、旁压试验现场比对,采用数理统计、相关分析,得到静力触探试验、旁压试验地基承载力计算的变异情况和相关程度。经过对比分析,提出福州地区静力触探试验地基承载力计算推荐公式,取得福州地区预钻式旁压试验地基承载力特征值修正系数经验值,供岩土工程从业人员参考。

Based on the field comparison test of static penetration test and lateral compression test carried out on the engineering survey project of Fuzhou rail transit under construction, the variation and correlation of bearing capacity calculation in static penetration test and lateral compression test are obtained by mathematical statistics and correlation analysis.Through comparative analysis, the recommended formula for bearing capacity calculation of static penetration test in Fuzhou area is proposed, and the empirical value of correction coefficient of bearing capacity characteristic value of foundation in pre-drilling lateral compression test in Fuzhou area is obtained as a reference for geotechnical engineers.
