按照规范通过对挤扩支盘桩单桩竖向极限承载力的试验,得到各桩的竖向抗压极限承载力。采用常用的三个计算抗压承载力公式对数据进行了理论计算,对计算结果进行对比分析,找出与实测数据出现较大差异的原因,确定了利用经验参数法确定支盘桩单桩竖向极限承载力的方法适合于本类试验的理论计算。 According to the specification, the vertical ultimate bearing capacity of each pile is obtained through the test of the vertical ultimate bearing capacity of the single pile of the squeezed branch pile. The commonly used three formulas for calculating compressive bearing capacity are used to calculate the data theoretically. The results of the calculation are compared and analyzed to find out the reasons for the big difference with the measured data. The method of empirical parameter method The method of ultimate bearing capacity is suitable for the theoretical calculation of this type of test.
