Characteristic Analysis and Construction of Railway's Loess Subgrade

路基本体与基床施工质量的好坏,是确保行车安全的关键,其填筑分层、摊铺碾压又是重要环节。文章围绕北同蒲增建二线工程DK227+800～DK228+650段的施工,从土质结构特征、检测方式与指标选定到施工及注意事项进行了论述,供类同工程借鉴。

The quality of the construction of subgrade itself and foundation b ed is the key of ensuring the driving safety, its placement in layers, spreading a nd rolling are the important links. Around the construction of a railway enginee ring, this paper discusses on soil structure, detecting method, targets selectio n, construction procedures and notable matters, which can be used for reference of the similar kinds of engineering.
