在已有的灰色单点预测模型理论的基础上,提出的实时动态灰色单点模型虽然在变形预测中得到了广泛的应用,但其仍然只是考虑的单点的变形情况,由于缺少点与点的空间关联性,往往得到的预测结果不理想。本文考虑到变形点之间的空间相关性,提出将残差修正应用于空间多点模型,引入实时动态空间多点残差修正模型。通过对远东国际机场广场基坑沉降点位移进行分析预测,取得了较好的效果。 Based on the existing gray single-point prediction model theory, the proposed real-time dynamic gray single-point model has been widely used in deformation prediction, but it is still only a single point of deformation considering the lack of points and points The spatial correlation often leads to poor predictions. In this paper, considering the spatial correlation between deformation points, this paper proposes to apply residual correction to spatial multi-point model and introduce multi-point residual correction model in real-time dynamic space. By analyzing and predicting the settlement of the foundation pit of Far East International Airport, the good results have been obtained.
