| 摘 要： | 静载荷试验是一项方法可行,理论上无可争议的桩基检测技术。在确定单桩极限承载力方面,它是目前最为准确,可靠的检验方法。为了进一步分析桩的荷载传递和承载力性状,预先在试验桩主筋上布置钢筋应力计以测量桩身轴向应力,在桩底埋设压力盒以测量桩端阻力。通过对实测数据的计算,便可得到试桩在各级荷载作用下的侧摩阻力和端阻力分布图,从而了解该桩的荷载传递和承载力性状。结合工程实践,通过对一工程三组测试桩静载荷实验及应力测试结果的分析,说明了桩-土的荷载传递机理。

| Abstract: | Static loading test was a testing techniques on pile foundations with feasible method and beyond controvercy theory.In term of determine ultimate bearing capacity,this is a best accurate and dependable test method.at present.For in-depth analysis of loading transfer and bearing capacity property on pile body,preliminarily we had arranged rebar stress gauge on trial pole main reinforcement to measure pile body axial stress and inbuilted stress box under the pile to survey tip resistance.By calculating actual measured data,the trial pile side friction resistance and end resistance distribution map had been gained at all levels loading action.Thus loading transfer and bearing capacity property on pile can be known.In this paper,combining three trial pile static loading with analysis of stress results,transfer mechanism on the pile-earth loading had been illustrated. |
