| 摘 要： | 利用有限的实测数据准确地预测桩的极限承载力具有重要的现实意义。根据灰色理论，建立了单桩荷载．沉降关系的GM(1，1)模型，介绍了运用灰色理论在有限的实测数据条件下预测单桩极限承载力以及完整的荷载．沉降关系的方法。通过工程实例的分析计算，证明该方法具有良好的预测精度，满足工程实际需要。

| Abstract: | It is of great significance for civil engineers to accurately predict the ultimate bearing capacity of single pile with the limited measurement data. Based on the grey theory,GM(1,1),a grey model of load-settlement relation for single pile is established. The prediction method of ultimate bearing capacity and the whole load-settlement curve are discussed in detail. The results of engineering cases prove that this method is reliable,and the precision of prediction can meet engineering need. |
