摘　　要：对垃圾堆体在正常含水率及浓缩液回灌后饱和含水率状态下的边坡稳定性进行分析,结果表明:垃圾土在饱和状态下密度增大,黏聚力减小,垃圾细粒之间相互摩擦力、咬合力迅速瓦解,导致垃圾堆体自然软化、蠕动、渐进破坏,最终引致滑坡。The slope stability of waste pile was analyzed under the normal moisture content and saturated moisture content after concentrated solution recirculation. The results indicated that the density of garbage soil increased under the saturated moisture content, the cohesion decreased, the friction and occlusal force collapsed. It resulted in the natural softening, wriggle and progressive destruction of waste pile, which led to the landslip at last.
