| Abstract: | According to the excavation features of Illite soft rock single-line railway tunnel,the paper adopts the elastic-plastic,non-linear and large deformation dynamic models and the common Drucker-Prager principle of geotechnical project,undertakes the numeric analysis by adopting ANSYS software,concludes the dynamic features and the sliding features of Illite soft rock from its displacement and stress,and the side wall support should be enhanced. |
