摘要

    摘要
  • 摘要: 为了研究水库初次蓄水过程中均质岸坡的塌岸现象，在室内建设了 4 类 9 个物理模型进行试验。试验结果表明，岸坡坡角越大、岸坡土体颗粒粒径越小，塌岸现象越易发生；凸形坡面岸坡比凹形坡面岸坡更易发生塌岸现象；覆盖层下伏基岩界线倾角越陡，越易发生塌岸现象。试验测得浸润线与理论计算结果的比较分析表明，浸润线的理论计算方法由于没有考虑岸坡土体的非饱和状态，可能过高地估计浸润线的位置
    Abstract: In order to investigate the homogeneous bank caving of reservoirs during the first impounding, 9 bank slope models divided into 4 types are made in the laboratory. The model test results indicate that the larger the angle of the bank slope, or the smaller the particle size in the bank slope, the more possible the bank caving. The collapse of the convex bank is easier than that of the concave bank. The larger the angle of the underlying bedrock, the more possible the bank caving. The typical phreatic lines in the model slope obtained from the experiments are compared with those obtained from a published analytic solution. The comparison indicates that the published analytic solution may over-estimate the elevation of the phreatic lines. The over-estimation may result from the neglecting of the unsaturated state of the bank soil mass in the analytic solution.
