摘要
渗流破坏是影响尾矿库稳定性的重要因素之一,对尾矿库工程的渗流进行研究十分必要。本文以某尾矿库工程为研究对象,通过现场勘察得到了该工程的基本状况,应用ANSYS软件对其副坝的渗流场、超孔隙水压力和渗透破坏情况进行模拟和分析。认为该尾矿库工程存在滑塌、尾矿砂液化及流土渗流破坏的可能,应该对其进行综合治理。并针对该尾矿库工程的治理提出了一些可行性建议。
Seepage failure is one of the important factors that affect the stability of tailings pond. It is necessary to study the seepage of tailings reservoir. In this paper, a tailings project is taken as the object of study. The basic condition of the project is obtained by field investigation. The seepage field, excess pore water pressure and osmotic damage of the auxiliary dam are simulated and analyzed by ANSYS software. It is believed that the tailings reservoir project has the possibility of slipping, tail- ings sand liquefaction and soil erosion, and it should get a comprehensive treatment and some feasible suggestions are put for- ward for the treatment of the tailings project.
