Research conclusions:(1)The landslides are usually of large scales with the obvious landslide characteristics and clear landslide elements. The landslide back wall are usually long and the surrounding boundaries are regulated by the combined cutting joints. (2)The landslide shape is related to the included angle between sliding direction and bedding rock tendency.(3)The geological alignment of the railway in this section should comprehensively consider the engineering situations in the section，and the principle of the”passing round first and then engineering treatment" should be followed. So the railway should be preferentially built in the right bank of the Qingjiang River to keep the railway away from the consequent slope. If the railway has to be built in the left band of the river, the best scheme with the least investment should be adopted.(4)The research results presented in this paper can be used for the railway alignment in the area with similar geological conditions to avoid the economic waste and construction risk due to the change of the schemes in later stage.
