严寒地区某尾矿库坝面排水沟设计要点

Design Points of Dam Surface Drainage Ditch of a Tailings in Severe Cold Area

针对尾矿库坝面排水沟常规设计时的不足,结合尾矿库现行规范规定,明确了坝面排水沟设计标准及平面布置原则,并对尾矿库常用的排水沟结构形式进行了对比分析。针对严寒地区某尾矿库坝面排水沟常规设计时存在的冻害严重问题,分析了尾矿库坝面排水沟设计要点,并讨论了提高坝面排水沟抗冻害能力的材料要求及结构形式,可为严寒地区尾矿库坝面排水沟设计提供参考。

In view of the shortcomings of the conventional design of the drainage ditch on the dam surface of the tailings pond,combined with the current specifications of the tailings pond,the design stan⁃dard and plane layout principle of the drainage ditch on the dam surface are clarified,and the structural types of common drainage ditches in tailings pond are compared and analyzed.In view of the serious prob⁃lem of freezing damage in the conventional design of the dam surface drainage ditch of a tailings pond in the severe cold area,the key points in the design of the dam surface drainage ditch of the tailings pond are analyzed,and the material requirements and structural types to improve the anti-freezing damage ability of the dam surface drainage ditch are discussed,which can provide reference for the design of the dam surface drainage ditch of tailings pond in the severe cold area.
