摘要
讨论了滑坡动态方向稳定性系数的概念，并在此基础上定义了滑坡的滑动方向和滑坡的稳定性系数。同时在滑坡数字地形图上通过逐次逼近的迭代算法完成了滑坡的稳定性系数的计算和滑坡滑动方向的确定。
The general formula about the calculation of downslide force and resistance to sliding in the arbitrary unit of landslide is deduced in the digital landform image. The sliding direction and stability coefficient of the landslide are defined based on the concept of dynamic directional stability coefficient for the landslide, while the stability coefficient and the sliding direction of the landslide may be determined in the digital landform image by utilizing the algorithm of gradually approaching.
