以某拟建赤泥堆场为研究区,选取合适的模拟计算参数及边界条件,在平面应变条件下,建立流体模型,利用FLAC~(3D)软件模拟坝体在无防渗、部分防渗、全部防渗设计条件下孔隙水压力分布、滤液渗流路径、渗漏量等,为该尾矿库的防渗设计提供技术依据。模拟结果表明:该软件能较好的模拟赤泥堆场尾矿坝渗漏情况,库区渗漏特性明显,因此为防止环境污染及保证尾矿坝的稳定性,应采用坝体和库区完全防渗措施,并应采用合适的防渗材料。此方法可为尾矿库安全防渗设计提供参考依据和指导施工。
Taking a proposed red mud yard as the research area, the appropriate simulation parameters and boundary conditions are selected to set up a fluid model under the condition of plane strain. FLAC 3D software is used to simulate the non-seepage and partial seepage control , The pore water pressure distribution under all seepage control design conditions, the seepage flow path of the filtrate and the amount of leakage and so on provide the technical basis for the seepage prevention design of the tailings dam. The simulation results show that the software can simulate the seepage situation of the tailing dam of the red mud yard and the seepage characteristics of the reservoir area are obvious. Therefore, in order to prevent the environmental pollution and ensure the stability of the tailings dam, the dam body and the reservoir area Complete anti-seepage measures, and should be suitable impermeable material. This method can provide a reference and guidance for the safe seepage prevention design of tailing ponds.
