摘要:
为提高尾矿库物理试验的科学性与可靠性，采用文献资料收集与分析方法，对国内尾矿库物理模型试验的研究现状与主要成果进行梳理和归纳；总结试验模型存在的问题与不足。结果表明：溃坝机理试验主要研究了管涌渗透、洪水漫顶、地震作用下的溃坝及其演化过程；下游演进试验主要揭示了溃坝过程中泥深、冲击力、流速、泄砂量、淹没范围等时空分布规律；稳定性评价试验主要利用物理试验得到的浸润线位置、尾砂沉积分布等数据建立数值模型，对尾矿库筑坝过程、不同工程状况下的稳定性进行分析；防护试验主要对坝体加筋及拦挡坝防护效果等进行研究。从溃坝机理与过程、溃坝主要影响因素、溃坝下泄物运移过程、物理模型设计和构建、监测技术和手段等方面提出相应的研究建议，供研究学者参考借鉴。
Abstract:
In order to improve the scientificity and reliability of the physical tests of tailings pond,the research status and main achievements of the physical model test of tailings pond in China were sorted out and summarize by using the literature document collection and analysis methods.The problems and shortcomings of the experimental model were summarized.The results showed that the research tests of dam break mechanism mainly studied the mechanism and evolution process of dam break caused by the piping seepage,flood topping,and earthquake action.The research tests of downstream evolution mainly focused on the mud depth,impact force,flow velocity,sand discharge amount,submerged range and other time and space distribution laws during the dam break process.The stability evaluation tests mainly used the data of the infiltration line position and tailings deposition distribution obtained from the physical tests to establish a numerical model,so as to analyze the stability of the dam construction process and different engineering conditions of the tailing pond.The protection tests mainly studied the reinforcement of the dam body and the protection effect of detention dam.The corresponding research suggestions were put forward from the aspects of the mechanism and process of dam break,the main influencing factors of dam break,the movement process of spilled material under the dam break,the design and construction of physical model,the monitoring technology and means,etc.,so as to provide reference for the researchers.
