摘要
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 test of the vertical ultimate bearing capacity of pile driving pile,the vertical compressive ultimate bearing capacity of each pile is obtained. Compressive bearing capacity formula is obtained by using the commonly used three data for the theoretical calculation,the calculation results are comparative analysis,finding out the causes of the appear bigger difference with the test data. To make sure the experience parameter method is used to determine the single pile vertical ultimate bearing capacity of squeezed branch piles method is suitable for this kind of test of the theoretical calculation.
