A rare earth mining area in Longnan County, Jiangxi Province, is affected by long-term mining operations and complex natural environments, and the slope stability problem is becoming increasingly prominent. Based on field investigation and data analysis, the geological and environmental conditions and slope stability characteristics of the study area were systematically evaluated. Physical and mechanical parameters of rock and soil mass were obtained through drilling, sampling and laboratory tests. Typical slope profile models were established by using Lizheng Geotechnical Software. On this basis, the circular slip method and broken-line slip method were adopted for computational analysis, and the slope stability under natural working conditions and rainstorm working conditions were simulated respectively. The calculation results show that under natural working conditions, the slope safety factor is 1.59, and the slope is in a stable state. Under rainstorm working conditions, the slope safety factor decreases to 0.913, and the slope is in an unstable state. Rainfall conditions significantly reduce the shear strength of soil mass and increase pore water pressure. Rainfall is the key factor triggering slope instability. The research results can provide a scientific basis for the formulation of slope protection measures in mining areas.

江西省龙南县某稀土矿区因受长期采矿作业及复杂自然环境影响,边坡稳定性问题日益突出。结合现场调查与资料分析,系统评估了研究区的地质环境条件及边坡稳定性特征。通过钻探取样与室内试验获取岩土体的物理力学参数,基于理正岩土软件构建典型边坡剖面模型,并采用圆弧滑动法与折线型滑动法计算分析,分别模拟天然工况与暴雨工况下的边坡稳定性。计算结果显示:在天然工况下,边坡安全系数为1.59,处于稳定状态;在暴雨工况下,边坡安全系数降至0.913,处于不稳定状态。降雨条件下显著降低了土体抗剪强度,提升了孔隙水压力,降雨是引发边坡失稳的关键因素。研究成果可为矿区边坡防护措施的制定提供科学依据。

江西省龙南县某稀土矿区因受长期采矿作业及复杂自然环境影响,边坡稳定性问题日益突出。结合现场调查与资料分析,系统评估了研究区的地质环境条件及边坡稳定性特征。通过钻探取样与室内试验获取岩土体的物理力学参数,基于理正岩土软件构建典型边坡剖面模型,并采用圆弧滑动法与折线型滑动法计算分析,分别模拟天然工况与暴雨工况下的边坡稳定性。计算结果显示:在天然工况下,边坡安全系数为1.59,处于稳定状态;在暴雨工况下,边坡安全系数降至0.913,处于不稳定状态。降雨条件下显著降低了土体抗剪强度,提升了孔隙水压力,降雨是引发边坡失稳的关键因素。研究成果可为矿区边坡防护措施的制定提供科学依据。

A rare earth mining area in Longnan County, Jiangxi Province, is affected by long-term mining operations and complex natural environments, and the slope stability problem is becoming increasingly prominent. Based on field investigation and data analysis, the geological and environmental conditions and slope stability characteristics of the study area were systematically evaluated. Physical and mechanical parameters of rock and soil mass were obtained through drilling, sampling and laboratory tests. Typical slope profile models were established by using Lizheng Geotechnical Software. On this basis, the circular slip method and broken-line slip method were adopted for computational analysis, and the slope stability under natural working conditions and rainstorm working conditions were simulated respectively. The calculation results show that under natural working conditions, the slope safety factor is 1.59, and the slope is in a stable state. Under rainstorm working conditions, the slope safety factor decreases to 0.913, and the slope is in an unstable state. Rainfall conditions significantly reduce the shear strength of soil mass and increase pore water pressure. Rainfall is the key factor triggering slope instability. The research results can provide a scientific basis for the formulation of slope protection measures in mining areas.
