摘　　要：为分析水库岸坡变形破坏特征,进行边坡稳定性评价,治理库区滑坡问题,本文以辽宁清河水库边坡为例,通过选择物理试验方法,将试验成果引入水库边坡稳定性分析,建立数值仿真边坡模型,计算清河水库在库水调度下的稳定性,以佐证模型结果的适用性。分析表明,利用物理模型试验,不仅可探寻出库水变动下,坡角和基岩角度不同的边坡对库水的反应,还可得到岸坡在库水作用下渗流场演变和岩土体破坏域变化的规律。在取得理想模型试验成果后,利用软件进行清河水库边坡稳定性数值模拟计算,得出边坡稳定性变化的一般规律,与物理模型实验成果互相论证解释。In order to analyze the deformation and failure characteristics of reservoir bank slopes and evaluate their stability to prevent and address landslide issues in the reservoir area,this paper takes the slope of Qinghe Reservoir in Liaoning as a case study.By employing physical experimental methods,the experimental results were integrated into the analysis of slope stability.A numerical simulation model of the slope was established to calculate the stability of Qinghe Reservoir under water scheduling conditions,thus verifying the applicability of the model results.The analysis shows that physical model tests can not only explore how slopes with different slope angles and bedrock angles respond to reservoir water fluctuations but also reveal the evolution of the seepage field and the transformation of failure zones under the influence of reservoir water.After obtaining the ideal experimental results,numerical simulations of the slope stability of Qinghe Reservoir were carried out using software.The general trends of slope stability changes were identified and validated through comparison with physical model experimental results.
