| 摘 要： | 将距离判别分析法(DDA)应用于岩体边坡稳定性预测中,建立了边坡稳定性预测的距离判别模型。模型选取重度、黏聚力、摩擦角、边坡角、边坡高度和孔隙水压力比等6个指标作为判别因子;以边坡实测样本作为训练样本,建立相应线性判别函数对待判样本进行分类。研究结果表明,距离判别分析模型是边坡预测的一种有效方法,可以在实际工程中应用。

| Abstract: | Based on the Distance Discriminant Analysis (DDA) method, a classification model of rock-mass slopes stability is established. Six factors are selected for synthetic evaluation of the stability of rock-mass slopes, including density, cohesion, friction angle, slope angel, slope height, and the ratio of pore water. Linear discriminant functions are obtained through training a large set of samples of slope stability. The results show that the classification model of distance discriminant analysis has excellent performance, and can be used in practical engineering. |
