| 摘 要： | 随着我国重载铁路及货车技术的发展,现行《铁路路基设计规范》（TB 10001-2005）中规定的铁路标准活载已不能完全满足重载铁路设计的需要.以西北某新建I级铁路项目为研究对象,研究了ZH活载作用以及列车行驶速度对铁路路基基床厚度的影响,对重载铁路路基基床厚度、类型及压实标准的选用起到了一定的参考作用.

| Abstract: | With the development of Chinese heavy haul railway and truck technology, regulations of railway standard live load cannot meet the need of heavy haul railway design in the current Code for Design on Subgrade of Railway （TB10001 - 2005 ）. Taking a new northwest grade I national railway project as the subject for the study, the paper analyzes the impact of ZH live load and speed of the train upon railway subgrade bed thickness, which played a certain reference role in selec-tion of heavy haul railway subgrade bed about thickness, type and compaction standard. |
