顾及开挖深度的灰色系统模型在基坑沉降预测中应用

Application of Gray System Model Considering Excavation Depth in Settlement Prediction of Foundation Pit

为提高基坑开挖过程中变形监测实时预测的准确性与可靠性,文章结合灰色系统理论,考虑关于监测数据与基坑开挖深度之间的关系,建立离散灰色系统模型,利用该模型对原始沉降数据进行分析预测,并通过实验数据对比分析得出,利用离散灰色系统模型预测的结果与实测数据相吻合,预测精度可靠,且具有一定的参考价值。

In order to improve the accuracy and reliability of the real-time prediction for deformation monitoring in the processing of foundation pit excavation, on the basis of Grey System Theory and considering about the relationship between the monitoring data and foundation pit excavation depth, the thesis built a model about Discrete Grey System, then used the model to predict and analyze the original settlement data. Finally by comparing and analyzing the experimental data,we drew a conclution that the predicted results of Discrete Grey System Model correspond with the measured data, the prediction is reliable, and it really has certain reference value.
