| 摘 要： | 文章收集郑西高速铁路地基黄土典型湿陷性试验资料(包括现场大型浸水试验及室内试验),以影响黄土湿陷系数主要因素为基础,运用MATLAB建立黄土湿陷系数的自适应神经网络模糊推理系统(ANFIS)预测模型。通过对样本的训练和预测,表明该模型预测结果与实际黄土湿陷系数十分接近。用多元线性回归法对这些非母体样品进行预测检验,经过对比ANFIS法优于多元线性回归法,证明ANFIS法是一种比较理想的预测方法。

| Abstract: | Based on the main factor influencing the loess collapsibility,the data of collapsibility test on collapsible loess foundation in Zheng-Xi High-Speed Railway are collected and summarized,a model of ANFIS based on the index about the loess collapsibility has been established in this paper.Compared the results with the conclusion by the method of multivariate linear regression,it is shown that the ANFIS prediction model could improve the accuracy of forecasting.The results shows that the prediction result afte... |
