    摘要

  • 影响黄土区人工边坡稳定性的因素具有复杂性与不确定性，难以通过单一方法作出客观准确的评价。为了研究山西太原古交市营立村采石场人工土质边坡稳定性，基于坡体工程地质条件采用模糊数学构建了模糊综合评价模型，进而结合相互关系矩阵评价其稳定性，最后通过FLAC3D 软件模拟分析了降雨条件下该土质边坡稳定性变化规律。结果表明：模糊数学理论评价营立村采石场人工土质边坡天然条件下稳定性系数为1.429（>1.15），处于稳定状态；FLAC3D 模拟显示天然状态下边坡稳定系数为1.426，日降雨量增加引起了浅层土体稳定性短暂上升后下降，降雨量150 mm/d时边坡稳定系数趋近于1，已处于极限稳定状态，可能诱发滑坡地质灾害。联合运用两种方法相互佐证能够提高评价准确性，使结果更符合边坡实际情况。

    The complexity and uncertainty of the factors affecting the stability of artificial slope in loess regions pose challenges for achieving objective and accurate assessments through a single method. To investigate the stability of the artificial soil slope at Yingli Village Quarry in Gujiao City, a fuzzy comprehensive evaluation model was constructed based on the engineering geological conditions of the slope using fuzzy mathematics. Subsequently, its stability was evaluated by integrating an interrelationship matrix. Furthermore, the stability change law of the soil slope under rainfall conditions was simulated and analysed by FLAC3D software. The results show that the fuzzy mathematical theory evaluates that the artificial soil slope of Yingli Village Quarry is in a stable state under natural conditions, with Fs =1.429>1.15. The simulation results of FLAC3D show that the stability coefficient of the slope in the natural state is Fs=1.426. Increasing daily rainfall briefly evaluates the stability of shallow soil layers, followed by a decline. When rainfall reaches 150 mm/d, the slope's stability coefficient approaches 1, indicating it has reached the limit of stability. This condition may trigger landslide disaster. The combined utilization of both methods enhances the accuracy of the assessment, aligning the results more closely with the actual slope conditions.
