基于空间变异性及沉积规律的尾矿库稳定性模型研究

为了突出尾矿空间变异性和离散型的重要性，本研究在尾矿库稳定性评估中特别考虑了这两个因素。传统的评估方法通常忽略了尾矿的空间变异性和离散性，导致评估结果不够准确。本研究采用现场勘查和地质材料试验确定了所需的物理力学参数，并利用GeoStudio软件建立了某尾矿库的渗流状态模型。通过Morgenstern-Price法和简化Bishop法计算分析了某尾矿库在不考虑尾矿的沉积规律及空间变异性、考虑尾矿的沉积规律、考虑尾矿的空间变异性三种情况下的不同工况稳定性模型。结果表明，突出尾矿空间变异性和离散型的创新点可以更全面地考虑尾矿的实际情况，提高评估的精度和可靠性，为尾矿库的安全管理提供更有效的技术支持。

Study on stability model of tailings reservoir based on spatial variability and sedimentary law

To highlight the importance of tailings spatial variability and discreteness, this study specifically considered these two factors in the stability assessment of tailings dams. Traditional evaluation methods often overlook the spatial variability and discreteness of tailings, leading to inaccurate results. This study determined the required physical and mechanical parameters through field exploration and geological material testing, and established the seepage state model of the tailings dam using Geo-studio software. The stability models of different working conditions were calculated and analyzed using the Morgenstern-Price method and the simplified Bishop method under three different situations: without considering the sedimentation law and spatial variability of tailings, considering the sedimentation law of tailings, and considering the spatial variability of tailings. The results showed that highlighting the innovation points of tailings spatial variability and discreteness can more comprehensively consider the actual situation of tailings, improve the accuracy and reliability of the evaluation, and provide more effective technical support for the safety management of tailings dams.
