基于岩石边坡稳定性评价方法CSMR体系,建立了边坡稳定性评价的判别分析模型,选用岩体质量、结构面特征、边坡几何条件等方面的综合指标作为判别分析模型的判别因子,以多个岩石边坡工程的稳定状况样本数据进行学习训练,建立了相应的线性判别函数对待判样本进行了预测。分析结果表明,判别分析模型评价边坡稳定性准确度高、误判率低,能够反映CSMR体系各参数对边坡稳定安全系数的影响程度,是一种有效的边坡稳定性评价方法。
Based on the CSMR system of rock slope stability assessment, a discriminant analysis model of slope stability evaluation is established. The comprehensive indexes of rock mass quality, structural plane characteristics and slope geometry are selected as the discriminant factors of discriminant analysis model. Multiple rock slope project stability of the sample data to learn training, the establishment of the corresponding linear discriminant function to be sentenced to the sample was predicted. The analysis results show that the discriminant analysis model can evaluate the slope stability with high accuracy and low false positive rate, which can reflect the influence of CSMR parameters on the safety factor of slope stability. Therefore, it is an effective slope stability evaluation method.
