裂土在我国广为分布,穿越裂土地区的铁路在修筑和运营管理中都遇到了大量的路基工程问题。本文就此,特别是路基边坡问题作为裂土研究的重点作了论述,进而详细地介绍了铁路裂土路基研究的进展情况,主要是铁道部两个有关裂土的重点科研项目的研究内容和所取得的研究成果;最后,提出裂土路基研究方面现存的一些急待解决的问题和相关的建议。 Cracks widely distributed in our country, across the cracked areas of the railway in the construction and operation management have encountered a large number of subgrade engineering problems. In this paper, especially the slope of subgrade as the focus of the research on the crack, and then introduced in detail the progress of the research on the railway cracked subgrade, mainly two key research projects of the Ministry of Railways on the rift, The research results obtained; Finally, some existing problems in the research of the roadbed on the soil and the related suggestions are put forward.
