摘要
通过收集上海地区典型工程试桩资料,统计应用黄强法及延伸线法计算的桩基桩侧摩阻、桩端阻力,与桩侧摩阻、桩端阻力的实测值进行对比分析.研究发现两种方法计算得到的端阻比大于实测值,且延伸线法结果离散性更大.故采用黄强方法打五折确定桩端阻力和桩侧摩阻力.
Abstract
Typical engineering pile test data in the Shanghai area was collected.The pile side friction and pile end resistance calculated by the Huang Qiang method and the extension line method,respectively,were compared with the measured values.It is found that the end resistance ratio calculated by both methods is greater than the measured value,and the dispersion of the extension line method is greater.Therefore,the Huang Qiang method is used to determine the pile end resistance and pile side friction resistance with a 50%discount.
