| 摘 要： | 用生物学领域生物生长的理念去研究单桩的静荷载曲线,引入4种生长曲线模型,并将其用于单桩荷载-沉降曲线的拟合和竖向极限承载力的预测,结果显示,生长曲线模型可以对桩的Q-S曲线进行拟合。结合工程试桩的实测资料分析认为,Richards生长模型拟合桩的静荷载曲线的适用性更广。

| Abstract: | Researching the single pile＇s static load-settlement curve by the biological growth views, and four growth curve models are used to fit the 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 five cases and the comparisons illustrate that the Richards model keeps good applicability in fitting the single pile＇s static load-settlement curve. |
