Abstract In this paper，the three cases of railway slopes，i. e. the relation between the creep of rock and the stability of Dong Yong He slide, the rock weathering and the stability of K190 slope and the blasting and deformation of high slope, are discussed, it may be indicated that the change of natural geological factors which influence on the stability of the railway slopes is a dynamic process. In order to ensure the long — term stability of the railway slopes，the dynamic process of the change of natural geological factors must be considered.
