大倾角基底排土台阶变形明显受到k的影响，k=0.3是一个转折点，基底处

The deformation of the dumping steps on the steep-angle basement is obviously affected by k, k=0.3 is a turning point, and the basement treatment significantly reduces the slope displacement, k>0.3, the displacement value is almost the same, k=0.3, k=0.6 is the dumping site deformation At the turning point of the direction, the increase of the k value causes the deformation and failure mechanics mode of the dump to change from creeping-cracking to creeping, and the tensioned area is basically the same as the cracked area in the project.

The deformation of the soil step of the large inclination substrate is obviously affected by k, k-0.3 is a turning point, the substrate treatment significantly reduces the slope displacement, k>0.3, the displacement value is almost the same, k-0.. 3, k-0.6 is the turning point in the direction of the deformation of the drainage field, k-value increase causes the deformation of the drainage field to destroy the mechanical mode from creep slip-pull to creep-slip, and the pulled area is basically the same as the crack area in the project.

K = 0.3 is a turning point, k > 0.3, the displacement value is almost the same, k = 0.3, k = 0.6 is the turning point of the deformation direction of waste dump. The increase of K value leads to the change of mechanical model of deformation and failure of waste dump from creep to tension crack, and the tensile area is basically consistent with the crack area in the project<br>
