变坝坡赤泥库漫顶溃坝模型试验研究
Experimental study on dam-break of a red mud reservoir with complex dam slopes
摘要
Abstract
Red mud is a kind of waste slag with unique properties discharged from alumina production.Therefore, red mud reservoir has special dam-break characteristic because of its extremely fine tailings particles. In this paper, a red mud reservoir and its downstream channel were studied as a whole, and the development process and mechanism of the overflow dam break about the tailings reservoir were analyzed by physical model test. The test results show that the dam-break development law of the red mud reservoir is relatively complex, and the process can be divided into three stages, and each stage has a trend of approaching dynamic equilibrium. In addition, the large change of dam slope results in the different partition phenomenon on the dam surface space. Finally, the formula for calculating the maximum submergence height of red mud flow in the downstream channel is derived and verified by model test data.关键词
