Field investigation of soil erosion was conducted on embankment slopes of both Qinhuangdao-Shenyang special line of passenger trains and Jiaozhou-Xinyi railway after precipitation

and factors leading to great difference of erosion degree between the two experimental plots were analyzed. The results indicate that difference between soil type of embankment slope of Qin-Shen special line of passenger trains and that of Jiao-Xin railway leads to the difference of soil erosion degree in the experimental plots. Due to containing coarse fragment

the degree of soil erosion on slope of Jiao-Xin railway is less than that on slope of Qin-Shen special line of passenger trains under the condition that single half-width rainfall is more than the critical single half-width rainfall. Soil erodibility of embankment slope is related to rainfall property. In the end of the paper

one suggestion was proposed to reduce soil and water loss on embankment slope.
