摘要: 以灰色系统理论中的GM(1,1)模型为基础,利用残差模型、等维新信息外延模型对其进行修正,实现了对单桩P-s曲线的拟合和极限承载力的预测,论证了以灰色系统理论对单桩承载力进行预测的意义。灰色预测具有要求数据少、计算简单而严密、精度高等优点。如借助于计算机进行计算分析,分析速度快,结果可信度高,因而在工程中具有较高的实际应用价值。

Abstract: Based on the model of GM（1,1） of grey system,the residual model and the equal dimensional new information model were used to modify it and the im itation of P-s curve and forcast of ultimate bearing capacity of the single pi le were implemented in this paper.And the grey model theory had a practical mea ning for the forecast of single pile.Less information,brief calculation and hi gh precision are the advantanges of grey forecast.With the help of computer,we can get the quick analysis,reliable forecast.So the grey forecast has a pract ical value in engineering.
