摘要
和常规铁路相比，高速铁路对基床表层功能的要求更加严格。对此，国外对基床表层都采用不同于传统方式的各种结构形式的“强化层”，但均随之提高了工程造价。因此选择一种适合我国高速铁路建设的经济、合理的强化基床表层十分必要。本文旨在通过对干硬性水泥稳定土材料的工艺及强度等性能的研究，试探其作为高速铁路基床表层的可行性。
The functional requirements on surface layer of foundation bed for high-speed rail-ways are rather more strict than for ordinary railways. In other countries,the stabilized layerswith various structure forms which are different from the traditional mode have been adoptedas the surface layer of foundation bed for high-speed railways,but the engineering costs areraised consequently.Therefore,it is very necessary to select a reasonable and economical sta-bilized surface layer which is suitable for the conditions of our high-speed railways. The tech-nology,strength and other properties of a dry-hard soil material stabilized by cement are re-searched in this paper. Based on the research,the realizability of using this material as thesurface layer of foundation bed for the high-speed railways has been discussed.
