摘要

为了保持轨道的平顺性和稳定性，高速铁路要求路堤的工后沉降为0。红层属于C类填料，易崩解、软化，依据单轴压缩蠕变（粒径小于2 mm和压实度为95 %）试验结果，对红层填料的蠕变特性进行了分析，同时基于工程应用的目的，根据蠕变曲线对路堤的工后沉降进行了预测，论证了采用红层作为填料在一定的施工工艺下能满足路堤工后0沉降的要求。

Abstract

In order to keep track even and steady in high speed railway

it is necessary for no embankment settlement after construction; but red beds are easy to collapse and soften

which belongs to stuffing for the third grade. Based on results of long-duration static test of simple compression without confining pressure (the grain size of sample is below 2 mm and compacting degree is above 95 %)

the creep characteristics of red beds are analyzed; and at the same time settlement after construction can be predicted by numerical algorithm for engineering applications. So it is proved that red beds can be served as stuffing with a certain construction methods and no settlement after construction is entirely fulfilled.
