双曲线法在单桩极限承载力预测中的应用

Application of forecasting ultimate bearing capacity of single pile by hyperbola method

对桩基工程来说准确计算出桩的极限承载力是非常重要的,通过对试桩的试验数据的处理,采用双曲线模型法对挤扩支盘桩的极限承载力进行预测,并利用实测数据对双曲线模型法进行修正,得到的计算数据与试验数据的拟合性非常高,说明双曲线模拟法适用于对挤扩支盘桩单桩极限承载力的预测。

For pile foundation engineering,it is very important to accurately calculate the ultimate bearing capacity of pile,the paper through the test pile test data processing,the hyperbola model method is adopted to predict the ultimate bearing capacity of the squeezed branch piles expansion,and uses the method of the measured data of hyperbolic model,the calculated data and experimental data fitting in the form of sex is very high,that hyperbolic simulation method suitable for squeezed branch piles expansion the prediction of the ultimate bearing capacity of the single pile.
