摘要
近些年受尾矿库选址及环境保护等政策的限制,新建尾矿库的工程投资明显增加,因此在原有堆坝高度上继续加高的工程增多,接近100~200 m级的高坝尾矿库大量涌现。为增加尾矿库的稳定性,以某尾矿库工程为例,坝体浸润线埋深较高,稳定计算不能满足相关规范要求。为有效降低浸润线,在堆积坝内采用大口辐射井和飘管相结合的排渗设施。经现场实际运行,排渗设施的应用对保证坝体稳定具有十分重要的作用。
In recent years,the project investment of the newly-built tailings pond is obviously increased by the limitation of the location of the tailings pond and the environmental protection,so the engineering increase of the newly-built tailings pond is increased,so that the high-dam tailings pond close to the level of 100~200 m has been formed in a large amount at the height of the original rockfill dam.To increase the stability of tailing pond,taking a tailing reservoir project as an example,the buried depth of the phreatic line of the dam is high,and the stability calculation can not meet the relevant specification requirements.In order to effectively reduce the phreatic line,the drainage facilities combined with the large-mouth radiation well and the drift tube are adopted in the stacking dam.The application of the drainage facilities plays an important role in ensuring the stability of the dam body through the actual operation of the site.
