【摘要】 位于九寨沟双河乡的草坪上滑坡属高烈度大型滑坡,一旦失稳,危害严重。通过对滑坡地质背景、结构特征和变形破坏特征的分析,确定该滑坡变形属重力蠕滑型。结合试验资料,通过参数反演确定计算参数,利用传递系数法对滑坡稳定性进行定量评价。评价表明,在天然、地震或暴雨工况下,滑体整体处于稳定状态。暴雨条件下,其前缘稳定性迅速降低,可能失稳。更多还原

【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.更多还原
