摘要: 针对规范中嵌岩桩竖向承载力的计算方法,所存在的问题和不合理之处,提出了用灰色预测系统理论对嵌岩桩单桩承载力的预测。根据灰色系统理论,建立了桩基工程GM(1,1)模型,结合桩基试桩实践,所得预测结果与实际结果吻合较好,经过精度检验,证明精度较高,为桩基工程承载力预测提供了一种可靠的理论方法。

Abstract: According to the method of the rock-socketed pile vertical bearing capacity in the norms, existing problems and unreasonable place are analyzed. The gray system theory of forecasting the vertical bearing capacity of rock-socketed pile is put forward. With the grey theory,the GM (1,1) model was established in the project of pile foundation. The testing result gears with forecasting result very well under the precise check. A theoretic method of forecasting the capacity in pile foundation is provided.

Key words: rock-socketed pile, vertical bearing capacity, norms, grey system theory, forecast
