拜耳法赤泥坝中无粘性土反滤层设计方法

Design of non-viscous earth proteciton layer for the red mud dam of Bayer process

国内的拜耳法赤泥堆场通常是采用土石坝作为初期坝,并在整个库区的范围内做无粘性土反滤层,用以防止土石坝被渗透破坏。如何设计反滤层,使其既有排水减压的作用,又有节约材料,施工时间短,侵占库容量小的优点。本文阐述了设计拜耳法赤泥堆场反滤层中的几个要点及工程实际应用情况。

Usually earth - rock dam is used as the initial dam of red mud stockpile of Bayer process, in which non - viscous earth layer is added to prevent it from damagina, The paper describes several issues about the design relating to the save of materials, shorter construction and less area.
