In order to solve the problem that the minimum buried depth of the phreatic surface in a uranium tailings dam is less than the code limit due to complex depositional structures and insufficient drainage facilities in the tailings dam, the numerical analysis on seepage and stability of the tailings dam were conducted by GeoStudio. The variation patterns of phreatic surface and factor of safety under normal, design, special water levels, with/without drainage consolidation measures, were systematically investigated. The results show that before the drainage consolidation measures were taken, the minimum buried depth of the phreatic surface is 1.74 m, 0.93 m, and 0 m under normal, design, and special water levels, respectively. Especially under the special water level, the phreatic surface emerged from the embankment above the 140.9 m platform. The factor of safety was 1.329, 1.321, 1.291 respectively before the drainage consolidation measures were taken. After setting up the horizontal drainage pipe as drainage consolidation measures, the phreatic surface burial depth increased by 3.48~4.59 m, while factor of safety at normal, design, special water levels rose to 1.431, 1.425, 1.402 respectively, with an increase of 7.68%~8.59%. The drainage consolidation measures can effectively optimize seepage conditions of the embankment, significantly reduce the phreatic surface elevation, and enhance dam stability, confirming satisfactory seepage control effectiveness. The results provide strong technical support for the design of drainage consolidation measures in tailings dams and offer valuable references for ensuring long-term safe operation of tailings ponds.

某铀尾矿库坝体沉积结构复杂、排渗设施设置不足,导致浸润线最小埋深小于规范限值。基于GeoStudio软件开展了尾矿坝渗流及稳定性数值模拟分析,系统分析了正常水位、设计水位、特殊水位下,采取排渗加固措施前后坝体浸润线、抗滑稳定安全系数的变化规律。结果表明:未采取排渗加固措施时,正常、设计、特殊水位下浸润线最小埋深分别为1.74、0.93、0 m,特殊水位下浸润线自140.9 m平台上部的堆积坝坡逸出;相应的坝体安全系数分别为1.329、1.321、1.291;设置水平排渗管进行排渗加固后,坝体浸润线埋深增加3.48~4.59 m,正常、设计、特殊水位下的安全系数分别增至1.431、1.425、1.402,增幅达7.68%~8.59%。排渗加固措施可有效改善尾矿坝渗流条件,显著降低坝体浸润线高度,提高坝体稳定性,渗流控制效果较好。研究成果可为尾矿坝排渗加固设计提供强有力的技术支撑,为尾矿库安全稳定运行提供参考。

某铀尾矿库坝体沉积结构复杂、排渗设施设置不足,导致浸润线最小埋深小于规范限值。基于GeoStudio软件开展了尾矿坝渗流及稳定性数值模拟分析,系统分析了正常水位、设计水位、特殊水位下,采取排渗加固措施前后坝体浸润线、抗滑稳定安全系数的变化规律。结果表明:未采取排渗加固措施时,正常、设计、特殊水位下浸润线最小埋深分别为1.74、0.93、0 m,特殊水位下浸润线自140.9 m平台上部的堆积坝坡逸出;相应的坝体安全系数分别为1.329、1.321、1.291;设置水平排渗管进行排渗加固后,坝体浸润线埋深增加3.48~4.59 m,正常、设计、特殊水位下的安全系数分别增至1.431、1.425、1.402,增幅达7.68%~8.59%。排渗加固措施可有效改善尾矿坝渗流条件,显著降低坝体浸润线高度,提高坝体稳定性,渗流控制效果较好。研究成果可为尾矿坝排渗加固设计提供强有力的技术支撑,为尾矿库安全稳定运行提供参考。

In order to solve the problem that the minimum buried depth of the phreatic surface in a uranium tailings dam is less than the code limit due to complex depositional structures and insufficient drainage facilities in the tailings dam, the numerical analysis on seepage and stability of the tailings dam were conducted by GeoStudio. The variation patterns of phreatic surface and factor of safety under normal, design, special water levels, with/without drainage consolidation measures, were systematically investigated. The results show that before the drainage consolidation measures were taken, the minimum buried depth of the phreatic surface is 1.74 m, 0.93 m, and 0 m under normal, design, and special water levels, respectively. Especially under the special water level, the phreatic surface emerged from the embankment above the 140.9 m platform. The factor of safety was 1.329, 1.321, 1.291 respectively before the drainage consolidation measures were taken. After setting up the horizontal drainage pipe as drainage consolidation measures, the phreatic surface burial depth increased by 3.48~4.59 m, while factor of safety at normal, design, special water levels rose to 1.431, 1.425, 1.402 respectively, with an increase of 7.68%~8.59%. The drainage consolidation measures can effectively optimize seepage conditions of the embankment, significantly reduce the phreatic surface elevation, and enhance dam stability, confirming satisfactory seepage control effectiveness. The results provide strong technical support for the design of drainage consolidation measures in tailings dams and offer valuable references for ensuring long-term safe operation of tailings ponds.
