摘　　要：应用临界滑移场技术,对排土场边坡进行临界滑动面搜寻.结果证明其边坡滑动面并非圆弧滑面;再应用临界滑移场技术的扩展方法进行反向搜寻,不仅可以得到排土场边坡的安全系数,还能求得边坡的最佳设计坡角.The critical sliding field technology was used to probe the sliding surface of a waste-dump slope. It is shown that the sliding surface of the slope is not a circular one. The reverse probing was carried out by using the expending method of critical sliding field, and the result show that both the safety factor and the optimum slope angle of waste-dump can be obtained.
