摘要
文中以某科技创新中心工程为沉降监测研究对象,运用灰色系统理论整体最小二乘法建立灰色系统模型,对变形过程进行模拟与预测,并对其预测结果评定精度,结果显示,该方法拟合精度等级为一级,在变形监测数据预测中具有一定的使用价值。
In this paper, taking a science and technology innovation center project as the research object of settlement monitoring, the deformation process was simulated and predicted using the grey system model established by the overall least squares solution of grey system model, and the prediction results were evaluated. Results showed that the fitting accuracy level of the method was one level, which had the certain use value in the prediction of deformation monitoring data.
