本文提出了确定试桩承载力以及把极限荷载划分为桩尖阻力和桩侧阻力的新方法。在试桩时,如量测加荷瞬间的桩顶沉降,就能定出桩尖的残余沉降。有了桩顶荷载与桩尖残余沉降的关系,就可以评定桩的极限承载力,并估计桩尖阻力和桩侧阻力。本文还提出了依据试桩P～S曲线划分桩尖阻力和桩侧阻力的试算法。对桩基的某些问题也作了简略的讨论。
This paper presents a new method to determine the bearing capacity of test piles and divide the ultimate load into pile tip resistance and pile side resistance. During test piles, residual settlement of the pile tip can be determined by measuring the settlement of the pile top at the moment of loading. With the relationship between the pile top load and the residual settlement of the pile tip, the ultimate bearing capacity of the pile can be assessed, and the pile tip resistance and pile side resistance can be estimated. This paper also proposes a test algorithm that divides pile tip resistance and pile side resistance according to test pile P~S curve. A brief discussion was also made on some issues of pile foundations.
