针对基坑支护结构变形监测数据的特点 ,建立了非等步长灰色模型 ,利用所建立的模型对支护的位移进行预测 ,结果表明预测值与实测值误差较小 ,说明了本模型具有较高的精度
According to the characteristics of deformation monitoring data of foundation pit supporting structure, a non-equal-step gray model is established and the displacement of the supporting structure is predicted by the established model. The results show that the error between predicted value and measured value is small, Higher accuracy
