摘要
介绍了四种路基沉降数据拟合方法和基本原理,并对实际工程的数据进行拟合,经比较得出适合郑西客运专线试验段工程的拟合方法,为高标准铁路路基的沉降量预测和铺轨时间的确定提供参考。
This paper introduces four data fitting methods and basic principles of subgrade settlement and carries out data fitting for the practical engineering to get the proper fitting method for pilot section project of Zhengzhou-Xi＇an passenger dedicated railway through comparison. It provides reference for determination of settlement prediction and tracking time of high-standard railway subgrade.
