一种新型复合边坡稳定性预测模型及其应用
|
摘要
提供了一种将模糊层次综合评价法和K-Means聚类方法相结合的新型边坡稳定性预测模型计算方法,并将该复合边坡稳定性预测模型应用于20个边坡样本中,预测准确率达到100%,验证了该模型的可靠性和实用性。传统极限平衡法所计算出的安全系数大于1并不能完全保证边坡工程的稳定安全,该复合边坡稳定型分析模型能有效的克服单纯安全系数预测边坡稳定性的局限性,为边坡的稳定性评价提供了新思路。
A new type of slope stability provides a fuzzy comprehensive evaluation method and KMeans clustering method combining forecasting model calculation method,and the model is applied in 20 samples of the composite slope stability prediction,the prediction accuracy rate of 100%,to verify the reliability and practicability of the model. The safety factor of the traditional limit equilibrium method to calculate more than 1 does not fully guarantee the safety and stability of slope,the slope stability analysis of composite type model can only forecast safety coefficient of slope stability limitations effectively overcome,provides a new approach for slope stability evaluation.
