摘　　要：以沪昆客专湖南段路基沉降监测资料为基础,提出基于指数函数的一种新的沉降预测方法:修正BiDoesResop模型,然后运用两类曲线进行曲线拟合分析,结果表明,修正BiDoesResop模型具有拟合精度高、适应性强等特点,对高速铁路路基工后沉降预测具有很好的指导作用。As the foundation of the monitoring data of settlement of Shanghai-Kunming passenger dedicated line Hunan section of subgrade, proposed modified BiDoesResop model as a new settlement prediction method based on exponential function. Then use these two kind of curve for curve fitting analysis, results show that the modified BiDoesResop model, has certain theoretical basis, high precision, strong adaptability, to play a direct role in settlement of high-speed rail subgrade.
