摘要
以某尾矿库为例,利用溃坝问题的数学模型和Fluent软件对尾矿库溃坝过程进行了模拟,对实际地形下尾矿库溃坝时尾矿砂浆的运动特点进行了研究.研究结果表明:在下泄尾矿砂浆分布形状,淹没范围扩散规律,溃坝波两侧运动能力、锋面速度变化等方面,实际地形对溃坝运动的影响明显,所采用的方法对实际工程具有参考价值.
This study took a tailings pond as an example.Fluent software was used to simulate the process of Tailings Reservoir Dam-break,and the motion characteristics of the slurry of tailing sand on the actual terrain were analyzed and studied when the tailings dam broke.The results showed that the actual topography has obvious influence on the movement of dam break mud.These effects included the distribution shape of discharged mud,the diffusion law of submerged area,the movement ability of both sides of dam break wave and the change of front velocity.The method used in this paper provides a reference for practical engineering.
