圆砾土填筑铁路路基压实质量标准研究

Compression Quality Standard and Technique Test Study of Thick Pellet Soil Used for Filling Railway Roadbed

我国现有铁路路基填方压实标准对粗粒土填料的压实质量控制仅有定性指标，使填方施工难于有效控制压实质量。本文介绍了在兰新复线施工中，针对这一问题填方工艺研究试验，制定出了兰新复线圆砾土填筑路基施工可行的压实标准。

There are standards of compression quality control for thick pellet soil filling intour railway roadbed filling compression standard, which is difficult to control compressionstandard in construction. In this paper,the filling technique of thick pellet soil is tested and thepractical compression standard of thick pellet soil used for filling Lanzhou to Xinjiang railwayroadbed is laid down.
