曲线高度拟合，Fs是关于k的一元二次函数，稳定系数变化规律如下，k>0

Curve height fitting, Fs is a one-dimensional quadratic function of k, and the stability coefficient changes as follows, k>0, that is, the substrate is treated by pocked blasting method. After the substrate is treated, the friction force on the dump site increases, and the sliding force is In the case of unchanged, the stability coefficient increases. As the value of k increases, that is, the treatment area of ​​the substrate continues to increase, and the coefficient of stability continues to increase. Because the shape of the dumping step in the large inclination area is triangular, as shown in Figure 3, when k continues to increase, the friction It keeps increasing but the increment decreases gradually, and the stability coefficient gradually tends to a constant value.

Curve height fitting, Fs is a binary function of k, the stability coefficient change law is as follows, k>0, that is, the use of hemp blasting method to deal with the substrate, the substrate treatment after the surface of the soil field by the friction increased, in the case of constant downward force, the stability coefficient increased. With the increase of k value, i.e. the base treatment area is increasing, the stabilization coefficient is increasing, because the shape of the drain steps in the large inclination area is triangular, as shown in Figure 3, in the case of k continuous increase, although the friction increases but the increase gradually decreases, the stabilization coefficient gradually tends to a constant value.

曲线高度拟合，Fs是关于k的一元二次函数，稳定系数变化规律如下，k>0，即采用麻面爆破方法处理基底，基底处理后排土场受到的摩擦力增大，在下滑力不变的情况下，稳定系数增大。随着k值增大，即基底处理面积不断增大，稳定系数不断增大，由于大倾角区域排土台阶形状为三角形，如图 3所示，在k持续增大的情况下，摩擦力虽然不断增大但增量逐渐减小，稳定系数逐渐趋向于一个恒定值。<br>
