| Abstract: | The landslide,a large-scale landslide of high-intensity located at Shuanghe Township of Jiuzhaogou,will cause serious hazards in case of instability.It is determined as a gravity-creep type through an analysis of its geological background,structural features and deformation-failure characteristics.The transfer coefficient method is applied to assess its stability quantitatively,with experimental data used and calculation parameters determined by the parameter inversion method.It is assessed to be stable as a whole in natural,earthquake or heavy rain conditions,yet with the possibility of its leading edge being unstable in storms. |
