| 摘 要： | 为探讨变权组合预测模型在变形监测中的应用,以监测某大坝沉降量为实例,研究基于线性回归预测模型和灰色模型GM(1,1)的变权组合。通过预测该大坝坝内沉降量,比较两种单一预测模型和变权组合预测模型的预测误差平方和,证明变权组合预测模型在沉降预测中具有更好的预测精度。

| Abstract: | In order to discuss the application of the changeable weight combination forecasting model to the deformation monitoring ,based on some dam’s settlement monitoring ,a model based on linear regression and grey model GM(1 ,1) is proposed .The result proves this method has better accuracy in predicting the settlement of the dam and calculating the sum squares of errors of one single forecasting method and the changeable weight combination forecasting model .This shows this model can provide a certain reference value for dam deformation prediction . |
