GM(1,1)模型在沥青路面平整度预测中的应用

Application of GM(1,1) Model in Prediction of Asphalt Pavement Smoothness

灰色系统是在贫数据状态下进行数据预测的数学方法。以黄(石)黄(梅)高速公路工程为研究对象,建立了沥青路面平整度GM(1,1)预测模型,对平整度的变化规律进行预测。结果表明,预测结果与实测结果的偏差能够控制在0.05 mm范围内,满足相关规范对施工预测精度的要求。

：The gray system is a mathematical method to predict the data in the state of poor data. In this pa- per,taking Huang -Huang highway project as the research project, GM （1,1）prediction model of asphalt pavement is built to predict the changing characteristics of smoothness. The results show that the deviation be- tween the predicted results and the measured results can be controlled within the range of 0.05 mm, which meets the requirements of the relevant specification for construction prediction accuracy.
