Calculation of dynamic directional stability calculation of dynamic directional stability for landslide in digital landform image 数字地形图上滑坡动态方向稳定性系数的计算与滑坡滑动方向的确定
2.
Stereographic technique is used in the analysis of the footwall slope in the open - pit of bangmoshan iron mine . the slope fracture mode and the slipping direction of unstable blocks are given and the stable slope angle is calculated to be 46 运用赤平极射投影的方法，对棒磨山铁矿露天采场下盘边坡进行了稳定性分析，给出了边坡破坏模式和不稳定块体的滑动方向，并推算稳定边坡角为46 。

The slide direction and distance of each block of landslide has been calculated quantitativily by the method of interactive interpretation and determination of specific points and the total volume of the landside unity is estimated out to be about 2 . 3 10 ^ 7m ^ 3 从三维角度出发，利用人机交互解译滑坡，求取特征点，分别对各部分滑体的滑动方向和距离进行了定量计算，估算出其体积约为2300万立方公尺。
