摘要
引用插值法将非等时距数据转化成等时距数列建立皮尔预估模型,并利用所建的皮尔模型对某隧道围岩变形情况进行了预测分析;结果表明,用皮尔曲线模型预测的围岩变形与实际围岩变形较为吻合。
This article quotes the interpolation to establish the Pearl Prediction model by transforming the non-equal interval date into equal interval series,and using it forecasting and analyzing the distortion of some tunnel surrounding rock.The result indicated that the forecasting deformation by the Pearl Prediction model is more con-sistent with the actual rock deformation.
