京沪高速铁路济南西客站软土路基沉降预测分析

Analysis on Settlement Prediction of Soft Soil Subgrade for Jinan West Railway Station of Beijing-Shanghai High-speed Railway

近年来,我国高速铁路发展突飞猛进,为保证安全运营,对其路基的处理尤其重要。对京沪高铁济南西客站软土路基工程的沉降数据,分别采用灰色模型GM(1,1)和双曲线模型两种方法建立了预测模型进行分析,并编程作数据处理。结果表明:灰色模型GM(1,1)对软土路基的沉降评估更显优越性。

In recent years,the high-speed railway in our country is developed rapidly.In order to guarantee safe running,the subgrade treatment is especially important.For the settlement data of soft soil subgrade for Jinan West Railway Station of Beijing-Shanghai High-speed Railway,the model for the prediction has been established with grey model GM（1,1）and hyperbolic model for analysis and data processing through programming.The result shows that the settlement assessment to soft soil subgrade with grey model GM（1,1）is superior.
