摘要

选用最易获得的标准贯入试验锤击数估算静力压入桩的沉桩阻力，提出了经验公式。对桩端阻力、桩侧阻力在土层中的变化等计算的细节问题进行了讨论，并编制了计算结果可视化的程序。2个工程实例的计算结果表明，用标贯锤击数估算静压桩沉桩阻力的方法是可行的，计算出的压桩力满足工程精度要求，可以方便的用于判断沉桩可能性、估算承载力、选择沉桩设备等。

Abstract

A series of static piling tests and SPTs were performed to investigate the behavior of jacked piles. The study focuses on the changing law of pile toe resistance and shaft resistance in different soil strata. Then an empirical formula is put forward to calculate the jacking resistance and a visual computer program is worked out. Two calculation engineering examples indicated that the method is feasible. The calculated jacking force satisfies the engineering precision requirement. It can be concluded that the method is convenient to judge driveability of pile

estimate the bearing capacity of pile and select the jacked piling equipment. The study is significant because the SPT data is commonly used can be easily obtained.
