摘要: 采用有限元分析方法,定性分析了初期坝排渗能力、尾矿堆积坝干滩长度、坝内各层渗透系数之比以及尾矿堆积坝下游坡比等因素对坝体浸润线的影响程度以及降低浸润线的措施,从而为尾矿库的设计、施工、运营提供了重要的技术依据,对保证尾矿库的安全运行意义重大。

关键词: 尾矿库, 渗流场, 浸润线, 初期坝

Abstract: A qualitative analysis was made on the factors affected the seepage line of tailing dam by FEM, which contained the drainage capacity of the initial dam, the dry beach length of fill dam, the ratio of osmotic coefficient for the layers in dam and the slope downstream of the fill dam factors.And the measures reducing seepage line are deduced.The technical basis is supplied for the design, construction and operation of the tailing dam, which is of significance for the safety operation of the tailing dam.

Key words: Tailing dam, Seepage field, Seepage line, Initial dam
