中文摘要:简要介绍路基沉降预测方法。根据厦深客运专线福建段第2标段D1K62+780的沉降观测数据对该断面进行指数曲线和双曲线拟合，将实测数据与拟合数据对比分析，得出指数曲线在沉降预测中相对于双曲线更加准确的结论。此外,指数曲线和双曲线拟合法相对于其他的沉降预测方法都要简单，便于工程技术人员的运用。

Contrastive Analysis on Exponential Fitting and Hyperbolic Fitting in Settlement Prediction of Soft Foundation
Abstract:Roadbed settlement prediction method is briefly introduced. According to the sedimentation data in a passenger dedicated line, exponential fitting and hyperbolic fitting were made. By the contrastive analysis on measured data and fitting data, exponential fitting was more accurate than hyperbolic fitting in settlement prediction. Being simpler than all other settlement prediction methods, exponential fitting and hyperbolic fitting are suitable for engineers and technicians.
