【摘要】 运用生物学领域生物生长的理念研究支盘桩的单桩静荷载曲线,引入四种生长曲线模型,对挤扩支盘桩的荷载—沉降曲线进行拟合以及预测桩的竖向极限承载力,结果显示,生长曲线模型可以对支盘桩的Q-S曲线进行拟合。结合工程试桩的实测资料分析认为,Weibull模型的拟合精度更高。更多还原

【Abstract】 The single squeezed branch pile’s static load- settlement curve is viewed from the biological growth law and four growth curve models such as Weibull,Richards,Gompertz and Logistic are used to fit the squeezed branch pile’s Q- s curve and then predict the ultimate bearing capacity of single pile. The results show that the growth curve models have a good effect on fitting the pile’s Q- s curve. These models are used to study six cases and the comparisons illustrate that the Weibull model keeps good applicability in fitting the single pile’s static load- settlement curve.更多还原
