【摘要】 单桩极限承载力的预测研究是近几年桩基础研究的一个热点。将灰色系统理论应用到抗拔桩的竖向抗拔极限承载力预测中。通过灰色预测方法,结合现场实测结果,对等截面抗拔桩的单桩竖向抗拔极限承载力进行预测分析,探讨了灰色预测方法在桩基极限承载力预测中的应用。更多还原

【Abstract】 The study on the prediction of ultimate bearing capacity of single piles is a hotspot in the research of piles foundation in recent years. This paper uses grey theory to predict the uplift ultimate bearing capacity of tension piles. By the grey theory, predict the ultimate bearing capacity of tension piles with uniform cross section. Compared with the result got from the in-situ test, it is proved that the grey theory is an effective method to predict the uplift ultimate bearing capacity of piles.更多还原
