以厦门地区大量的沉管灌注桩现场轴向静荷载试验资料为依据，假定Ｐ一Ｓ曲线符合双曲线方程，用回归分析方法导得沉管灌注桩单桩竖向极限承载力的统计公式。
Based on the field static axial load test data of a large number of immersed cast-in-place bored piles in Xiamen, based on the assumption that the P-S curve conforms to the hyperbolic equation, a statistical formula for the vertical ultimate bearing capacity of a single pile of a cast-in-place bored pile is obtained by regression analysis.
