【摘要】 根据在南芬铁矿 2号排土场东沟门所测绘的地形图 ,以 1 2个不同的坡角对该边坡进行了稳定性的数值模拟分析 ,力求找到稳定性最好 (坡角最小 )和排土场库容最大 (边坡坡角最大 )二者的最佳结合点 ,并对该排土场可能产生的各种破坏模式进行了评估。更多还原

【Abstract】 According to the relief map mapped in the No.2 dump of Donggoumen of Nanfen Iron Mine,the stabillity’s numerical stinulation analysis of the slope was carried oat from 12 different grading angles,so as to find out the best joint point with the best stability (minimum grading argle)and the maximum capacity of the dump (maximum grading angle of the slope).The possibility of various destroying modes for the slope was evaluated.更多还原
