桩基极限承载力预测研究

Study on the Prediction of Plie's Limit Bearing Capacity

为了使桩基设计更加合理可靠,在分析桩基静载试验Q-S曲线性质的基础上,采用一元多项式对桩基的Q-S曲线进行拟合及预测。实践表明,一元多项式能较好地拟合桩基的Q-S曲线,并可准确地对其极限承载力进行预测。

For the purpose of improving the rationality and reliability of pile design, on the basis of analyzing the characteristic of pileb static load Q - S curve, a ＂one element multi item format＂ is adopted to fit and predict a pile＇s Q -S curve. The practice indicates that ＂one element multi item format＂ can properly fit pile＇ Q -s curve and accurately predict its limit bearing capacity.
