Abstract Based on a lot of field geological investigation, sample test and analysis research for the swelling rock on cut slope of several railway lines in China, according to the complexity of swelling rock and the development of slope defects, a comprehensive evaluation standard for rock swelling property has been established, which has the relationship between the free swell of rock silt (Fx)with the dry saturated hydroscopic moisture ratio of rock (Rdw).The engineering design rule for the swelling rock cut slope has been put forward also in this paper.
