| 摘 要： | 路基沉降是高速铁路设计和施工中所要考虑的主控因素。结合沉降观测数据可以对路基沉降量进行预测。通过预测可有效保证高速铁路路基工程达到规定的变形控制要求，以合理确定无砟轨道的铺设时间。而路基沉降预测常用方法涉及多个学科和领域，工作难度大，是长期以来困扰高速铁路施工技术人员的难题。此文介绍了高速铁路路基沉降预测的几个典型方法，极具代表性，有一定参考价值。

| Abstract: | Subgrade settlement is main controlling factor for designing and engineering of high-speed railways.Combining with subgrade settlement observation data,we can predict settlement amounts so as to ensure deformation controlling requirements as well as reasonably determines laying time of unballasted tracks.This paper introduces several typical measures of settlement predictions of high-speed railway which have some reference value. |
