摘要: 为探究能同时预警滑坡时间和区域的方法,基于均值-标准差分类法及加权马尔科夫链理论,提出一种新的滑坡预警判据,构建对应的滑坡预警模型,同时给出预警模型评价标准。以平庄西露天矿顶帮“4·17”滑坡为工程实例,选择样本容量n为20,标准差倍数k为0.4,分析滑坡区域附近28个监测点的滑坡预警效果。结果表明,该预警模型有良好的时间预警和区域预警效果,预警模型对滑坡区域内监测点的平均7日预警密集度为77%,对滑坡区域外监测点的平均7日预警密集度为6%,对全部监测点的平均错误预警率为0,平均预测一致率为61%。

Abstract: For the sake of exploring the landslide warning method which can achieve early warning for the time and area, a new landslide warning criterion was established, and a weighted Markov chain theory based model was built for landslide warning ,and an evaluation criterion was established for early warning.The model was applied to the 4.17 landslide on top slope of Pingzhuang west open-pit mine as the engineering background. The landslide warning effects of 28 monitoring points near the landslide area were analyzed with sample size n was 20 and standard deviation ratio k was 0.4. The results show that the landslide warning model has a good effect in both time early warning and region early warning . The average warning intensity of 7 days is 77% for the landslide area and 6% in outside of the area, the average error warning rate is 0 and the average rate of consistency in predicting is 61% for all monitoring points.

Key words: landslide early warning, Markov chain, warning intensity, error warning rate, rate of uniform
