fs是关于k的一元二次函数，随着k值增大而增大，但逐渐趋向于一个定值，其根本原因是基底在麻面爆破后，摩擦力增大，在下滑力不变的情况下稳定系数变大。但由于大倾角区域排土台阶形状为三角形，当k不断增大至1时，增加的处理区域对应的排土台阶体积逐渐减小，重力减小，摩擦力增量减小，所以在下滑力不变的情况下稳定系数增量减小逐渐区域一个定值。

FS is a binary quadratic function of K, which increases with the increase of K value, but tends to a fixed value gradually. The root reason is that the friction increases after the blasting of the base in the surface of the hemp, and the stability coefficient increases with the constant sliding force. However, the shape of the soil discharge step in the large dip area is triangle. When k increases to 1, the volume of the soil dumping step corresponding to the increased treatment area decreases gradually, the gravity decreases and the friction force decreases. Therefore, the increment of stability coefficient decreases gradually in the region with the constant sliding force.<br>
