摘　　要：在考虑人工排土场松散高边坡基本特征、变形破坏方式等的基础上,采用因素敏感性分析法,计算讨论了影响排土场高边坡稳定的主要因素--坡体几何形态特征、日常爆破震动、水等因素的变化对其稳定性的影响程度,确定了坡体几何形态特征因素为影响其稳定性的关键因素以及在确保排土场高边坡稳定条件下的单台阶合理坡角、坡高、预留宽度等人工堆积参数及最大堆积高度。This article is based on the basic characters and deformation styles etc of the loose fill slope with great height. It takes the way of gene sensitive analysis to calculate and discuss effect degree for the major factors to the stability of the high slope. The factors include geometric features of the slope, daily blasting vibration and water. They are used to determine the geometric features of the slope as the key factor to its stability. Then It puts forward the proper angle, height and the reserved width, artificial deposits parameters and the maximum deposit height of the slope under the condition of the stable dump slope.
