摘要:
关于干式堆存尾矿库防渗方式与三维渗流分析之间的研究很少。某干式尾矿库设计采用初期坝内坡及库区整体防渗，碎石排渗井及排渗褥垫排渗,使用Autobank_3d建立三维模型,进行有无排渗褥垫条件下的浸润面及浸润线分析。结果表明:未布设排渗褥垫时,下游坝坡右岸拐弯处浸润面埋深较浅,并有出逸区域出现；布设排渗褥垫后,浸润面的埋深能达到12 m以上,即排渗褥垫对渗流影响显著。

Abstract:
Few pieces of research are carried out on the anti-seepage mode of dry stacking tailings ponds and 3D seepage analysis.A dry stacking tailings pond was designed to carry out early dam internal breaking and overall anti-seepage within the pond area,and discharge seepage with gravel discharge wells and discharge pads.Autobank 3D is used to establish a 3D model and analyze the seepage face and seepage line in the absence of seepage discharge pads.The results show that without seepage discharge pads,the seepage face is buried shallow at the turning of the right bank of the downstream dam slope and runaway areas appear;with seepage discharge pads,the burial depth of the seepage face can reach over 12 m,which means that the seepage discharge pads have a great influence on seepage.
