| 中文摘要: |
| 根据不完全的竖向静载试验数据，利用灰色系统理论的GM(1,1)模型预测单桩的竖向极限承载力，并对结果的合理性及误差进行分析.工程实例分析表明，竖向静载试验所施加的荷载达到或超过极限荷载的四分之三时，利用其数据进行单桩竖向极限承载力的预测具有较高的精度.同时新信息GM(1,1)模型、新陈代谢GM(1,1)模型比老信息GM(1,1)模型预测的结果更精确. |
| 英文摘要: |
| According to incomplete data of the single pile on the vertical static loading test,this research aims to predict the vertical utmost bearing capacity of the single pile by GM (1,1)model of the gray system theory,and to analyze the reasonableness and error of results.Analysis about a practical engineering example indicates that the prediction of the vertical utmost bearing capacity of the single pile by the test data has comparative accuracy when the load reaches or exceeds the utmost bearing capacity of tree-quarters during the vertical static loading test,also the new information GM(1,1)model and the metabolic GM(1,1)model have more accurate prediction than the old information GM(1,1)model. |
