摘　　要：针对水库粘土铺盖渗漏问题,在"土坝粘土铺盖裂缝淤填自愈"模型试验的基础上,对裂缝淤填过程中渗透系数的变化规律进行分析,进一步说明"淤填自愈"的先进性与可行性。Considering the seepage problem of reservoir clay blanket and based on model testing of crack silting and self-healing of earthfill dam clay blanket, the variation law of permeability coefficient during crack silting is analyzed and the sophistication and feasibility of 'silting self-healing' is further demonstrated.

关 键 词：土坝 粘土铺盖 裂缝 固结 淤填自愈
