Chinese Abstract

本文采用上游式筑坝工艺制作尾矿坝室内物理模型,并基于相似理论在该模型上进行模拟降雨漫顶的溃坝试验,重点研究了上游式尾矿坝漫顶溃坝过程中的溃口扩展机理.分别得到了溃口深度与时间的变化关系和溃口顶宽与时间的变化关系;同时,模型试验显示溃口顶宽出现间歇性的展宽现象,理论分析了出现该现象的机理.该研究不仅完善了上游式尾矿坝漫顶溃坝的机理,同时对尾矿坝事故的防灾减灾工作提供了指导.

English Abstract

The dam overtopping rainfall simulation experiment was carried based on similarity theory, focuses on the upstream tailings dam overtopping dam during the break expansion mechanism. The relationship between the breach depth, breach top width and time change respectively are obtained. At the same time, the model tests show that the breach appears top width broadening intermittent. The mechanism of this phenomenon is analyzed. This study not only perfects the mechanism of overtopping failure of tailings dam, but also provides guidance for the disaster prevention and reduction of tailings dam accident.
