高铁路基沉降预测新方法的研究与探讨

New Method of High Speed Railway Subgrade Settlement Prediction

透过高速铁路路基的工程实例,利用Natton预测模型,对路基的后期及最终沉降进行预测,同时将预测数据与实测数据进行拟合分析对比,结果表明,Natton预测模型具有精度高、适应性好等特性,因此,可以作为地基沉降预测的新方法广泛地运用于实践之中。

By combining the high-speed railway subgrade project example and using the Natton prediction model,the study predicted the late and final settlement of the roadbed,while fitting and comparing the predicted data and measured one.The result shows that,the Natton prediction model has the high accuracy,and good adaptability.Therefore,it can be used to forecast foundation settlement which can be widely used in practice.
