Pearl模型在高速铁路路基沉降预测中的应用

Application of Pearl Model in High-speed Railway Subgrade Settlement Prediction

根据高速铁路路基沉降量与时间关系的特点,建立了Pearl预估模型对高速铁路路基沉降量进行预测,对京沪高速铁路昆山试验段的沉降预测表明,该方法预测结果与实际较为吻合,可为高速铁路路基沉降预测提供一种有效而实用的方法。

According to the characteristics of relationship between high-speed railway roadbed setting amount and time,The Pearl Prediction Model which can predict railway roadbed setting amount was established.The setting amount prediction of Kunshang trial road of Beijing-Shanghai high-speed railway was conducted.The experiment results show that prediction outcome basically coincided with the practice.This is an effective and useful way to develop high-speed railway roadbed setting prediction method.
