摘　　要：渐进性破坏随机法能很好反映边坡体内局部破坏的产生、扩展及对边坡整体可靠性的影响。本文介绍了渐进破坏性随机法基本原理及分析过程基础,并应用于贵州某滑坡体实例研究。结果表明,与工程经验相符,是实际可行的边坡稳定性分析方法。Random methods of gradual failure can truly reflect the generation, extention of partial failure, and effect to entire reliability. Based on the introduction of foundamental principle and analytical process about random methods of gradual failure, a slope in Guizhou is discussed. The conclusion of this method is in accordance with the result of methods of imparting factors, and in accordance with project experience. It shows that random method of grandual failure is feasible in practice.
