| Abstract: | In combination with the specific example of unstable slope treatment project in the left bank of Sequ River in Dege City,Ganzi Tibetan Autonomous Prefecture,Sichuan Province,and through the geological survey,the authors identify the slope topography,formation lithology,structure characteristics of rock and soil and hydrogeology conditions.On this basis,the deformation mechanism and the possible failure modes of slope are studied,and the slope stability is evaluated.According to the results of the study,the treatment proposal of the unstable slope is proposed,which should provide for the strategic decision in geological disaster defense. |
| Keywords: | unstable slope deformation mechanism failure model stability evaluation Dege county Sichuan Province |
