摘要
影响泥石流沟性质的因素繁多,如主沟长度、流域面积、流域最大高差等,故泥石流的分类是受诸多因素影响的多维非线性问题,对泥石流分类可以对泥石流危险度划分及防治对策等提供较好的建议,本文结合FCM(模糊C均值聚类)法,根据现场调查的泥石流沟各因素值划分泥石流沟的类别,以现场调查及工程经验证明分类结果较好反映泥石流沟的实际情况,证明了该方法的有效性及可行性。
There are many factors that affect the feature of debris flow gullies, such as length of the gully, watershed area, maximum altitude difference , so the cluster of debris flow gullies is a many dimensions nonlinear problem. Cluster of danger potential and Guard measures can be proposed according to result of debris flow cluster. In this paper, FCM is used to cluster field factors that choosed,and from the resuh of field investigation and engineer experience, the result of cluster well coincide with practical situation of debris flow vullies, so this method to analyze is useful and feasible.
