改良土问题是高速铁路路基的重要内容,通过大量的土工试验和理论分析,研究石灰改良黄土的击实特性、压缩特性、强度特性以及影响因素,论证石灰改良黄土作为高速铁路路基基床底层填料的可行性,为黄土地区铁路客运专线路基填料的选择和应用提供参考依据。
The improved soil is an important part of the high-speed railway subgrade. Through a lot of geotechnical tests and theoretical analysis, the compaction, compression and strength characteristics of lime-improved loess and its influencing factors are studied. Lime-modified loess as the underfill of high speed railway subgrade Which can provide references for the choice and application of roadbed packing in railway passenger dedicated line in loess area.
