摘要
采用指数方程式Q =Qm(1-e-as)来模拟桩的静载荷试验Q -S曲线 ,应用变尺度的DFP法即 (Davidon -Flether -Powell)优化方法对大量试桩资料进行分析 ,指出预测灌注桩单桩的Q -S曲线以及极限承载力。实践表明 。
Simulate Q～S curve of pile by using equation Q=Q m(1- e -as ). Large amount of data for test piles are analyzed by adopting DFP(Davidon-Flether-Powell) method of optimization. Q～S curve and predicting capacity of cast-in-place piles are proposed. Application shows that this method is workable.
