| 摘 要： | 提高传统单桩承载力的灰色预测法的预测精度是非常有现实意义的。以灰色理论为基础，先对有限实测数据进行筛选，建立单桩荷载-沉降关系的优化GM(1，1)模型，介绍一种在有限实测数据条件下高精度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，证明该法具有的预测精度较传统灰色法提高3倍以上。

| Abstract: | It is of great significance to improve the accuracy of tradition grey prediction of ultimate bearing capacity of single pile.Based on grey theory,optimized GM(1,1) model of load-settlement relationship for single pile is established after selecting the limited measured data.A high-accuracy prediction method of ultimate bearing capacity and the whole load-settlement curve of single pile with limited measured data is discussed in this paper.Through engineering examples,it is proven that the precision accuracy... |
