Abstract:

尾矿坝是矿山的一个重要设施，同时也是危险性较大的设施。在尾矿坝的破坏中，渗流破坏是一个很重要的原因。为研究尾矿坝的渗流状态，对尾矿坝进行合理的设计及管理，以某尾矿坝为例，采用Geo-Slope软件，考虑正常蓄水位、校核洪水位、水骤降至死水位三种不同的工况，对其进行渗流场与耦合渗流场的对比分析，模拟出了工程中的实际渗流问题，分析了孔隙水压力、渗流速度、总水头等的变化规律。该研究可为尾矿坝的稳定性分析提供依据。
Seepage damage is one of the main causes of tailings dam failures. In order to study the seepage state of the tailings dam and carry out reasonable design and management of the tailings dam, a tailings dam was taken as an example. Geo-Slope software is used to consider the normal water level, check the flood level, and the water suddenly drops to death. The seepage field and the coupled seepage field were compared and analyzed for three different working conditions of water level, the actual seepage problem in the project was simulated, and the variation laws of pore water pressure, seepage velocity, and total water head were analyzed. This study can provide a basis for the stability analysis of tailings dams.
