摘要

为了验证用《建筑桩基技术规范》中的公式计算开口钢管桩竖向承载力的合理性,以具体工程为实例,采用规范中的计算公式、MIDAS数值模型和高应变现场检测的方法,对开口钢管桩的竖向承载力进行了比较分析。结果表明:按规范中的计算公式计算得到的竖向承载力明显大于现场检测值;按数值模型分析得到的竖向承载力小于规范中公式的计算值。
In order to prove the reasonableness of the formula of calculating the vertical bearing capacity of open-ended steel pipe piles in "Technical Code for Building Pile Foundations",we take a specific project as an example and comparatively analyze the vertical bearing capacity of open-ended steel pipe piles using the regular computational formula,MIDAS numerical model and high-strain field testing.The results show that the value of vertical bearing capacity calculated with the computational formula in the technical code is significantly larger than that of the site test;while the vertical bearing capacity analyzed with the numerical model is less than the calculated value by the formula in the technical code.
