排土台阶变形、塑性区发展易受k值影响，在k值恒定的情况下，不同处理区域

The deformation of the dumping step and the development of the plastic zone are easily affected by the value of k. When the value of k is constant, the number of different treatment area groups j obviously changes the slope deformation, and the increase of j leads to a sharp decrease in the shear strain increase in the slip surface area. Small, but when j increases to a certain value, the amount of change in shear strain increment will be small. The incremental change of shear strain indicates that the main damage of the contact surface occurs in a specific area, and the position will not change due to the change of j. The increase of j makes the increase of shear strain tend to a value, and the change of j makes the destruction of the entire dumping step. The form changes. Figure 10 shows that when j is a fixed value, the sliding range along the contact surface is constant. Under the condition of j=12, the change of the shear strain increment indicates that the sliding range along the contact surface is further expanded. It can be seen from Figure 14 that the slope displacement is also affected by the change of j value, and the change law is the same as the shear strain increment, but j does not change the displacement direction.

Draining step deformation, plastic area development is susceptible to k value, in the case of constant k value, the number of different treatment area groups j obviously changed the slope deformation, j increase led to a sharp decrease in the shear strain in the sliding area, but when j increased to a certain value, the amount of shear strain incremental change will be very small. The change of shear strain increment indicates that the main damage of the contact surface occurs in a specific area, the position does not change due to the change of j, the increase of j value makes the shear strain increment tend to a value, the change of j makes the destruction form of the entire drainage step change, Figure 10 shows that when j is a fixed value, the sliding range is constant along the contact surface, and the change in the shear increment under j-12 conditions indicates a further expansion of the sliding range along the contact surface. As can be known from Figure 14, the slope displacement is also affected by the j-value change, the law of change is the same as the shear-strain increment, j but does not change the displacement direction.

The deformation and development of plastic zone are easy to be affected by K value. In the case of constant K value, the number of different treatment areas J obviously changes the slope deformation, and the increase of J leads to the sharp decrease of shear strain increment in sliding surface area, but when J increases to a certain value, the change of shear strain increment will be very small. The change of shear strain increment shows that the main failure of the contact surface occurs in a specific area, and the position will not change due to the change of J. the increase of J value makes the increment of shear strain tend to a value, and the change of J changes the failure mode of the whole dump bench 10 indicates that the sliding range along the contact surface is constant when J is a constant value, and the change of shear strain increment under the condition of J = 12 indicates that the sliding range along the contact surface is further expanded. It can be seen from Figure 14 that the slope displacement is also affected by the change of J value, and the variation law is the same as the shear strain increment, but J will not change the displacement direction.<br>
