摘要
运用灰色理论对预应力锚索抗滑桩预应力监测数据进行分析,建立GM(1,1)模型和改进的GM(1,1)模型,对锚索预应力变化进行预测。GM(1,1)模型与改进的GM(1,1)模型预测结果与实际监测结果均吻合良好,均能够达到合格的标准,并且改进的GM(1,1)模型比GM(1,1)模型计算精度要高。基于灰色理论的预应力锚索抗滑桩预应力损失预测是可行而实用的,具有较高的可靠性,灰色预测较为客观地反映了工程实际情况,对边坡稳定的预测预报有一定的参考价值。
It was using grey theory to analysis the monitoring data of the prestressed anchor cable anti slide pile, establishing the GM （1, 1） model and improved GM （1, 1） model to predict the change of the prestress. The GM （ 1, 1） model and improved GM （ 1, 1） model prediction results with the actual monitoring results were both in good agreement, both can reach the standard of qualified, and the improved GM （ 1, 1） model had higher accuracy than the GM （ 1, 1） model. Based on the grey theory to predict the prestressed loss of the prestressed anchor cable anti slide pile was feasible and practical, which had high reliability, grey prediction was objectively re- flected the practical engineering, the prediction had a certain reference value on the forecast of slope stability.
