摘要
针对施工路基沉降情况进行分析,本文利用灰色理论中的灰色线性回归模型和灰色Verhulst模型对路基沉降情况进行研究预测。由于沉降数据属于S型数列,在MATLAB9.0平台上利用MATLAB语言对上述两种模型编程后分别进行实例检验,研究结果表明灰色Verhulst模型相对灰色线性回归模型更适合于S型序列的数据分析预测。该模型能够更好地反应沉降趋势,符合S型序列的分布特征,分析预测精度较好,可为监测提供有效的信息。
According to the analysis of the construction of roadbed settlement,this paper predict the roadbed settlement with grey linear regression model and Verhulst grey model.The settlement data belongs to the S type series,the two models are tested using programming with MATLAB language in MATLAB 9.0platform.The results show that the Verhulst grey model is more suitable for S sequence data and can better respond to the settlement trend,consistent with the distribution characteristics of S sequence analysis,and higher forecast accuracy.It can provide effective information for monitoring of settlement.
