摘要
利用灰色系统理论,对秦山核电站一期海堤沉降进行了预测,以较少的观测样本建立了新陈代谢数列,经后验差检验,观测精度达到一级。由此证明,用GM(1,1)模型进行预测,建模方便,预测精度高,在大型建筑物变形监测中有较大的实用价值。
In this paper. dam subsidence of the Qinshan nuclear power station is forecasted by using the gray system theory, meanwhile the new superseding the old data is established by making use of a few observation examples and variance tests show that the accuracy of residual comes to the first level. Therefore it's proved that the construction of model is simple and convenient, and the forecasting accuracy is high using the GM (1, 1) model to forecasting subsidence. It can be used in the adjustment and prediction for the deformation monitoring network.
