内蒙古砒砂岩的模糊聚类分析

Fuzzy Cluster Analysis of Soft Rocks in Inner Mongolia

由于不同种类砒砂岩的风化与侵蚀程度不同,对其抗侵蚀性的研究需要对岩样进行科学的分类。采用模糊聚类多元统计分析方法,通过Matlab语言实现该方法并将其应用于内蒙古砒砂岩的分类,将研究区的砒砂岩大致划分为9大类,分别为紫红色砂岩夹灰绿色泥岩、紫红色砂岩、紫红色砂岩与灰白色砂岩互层、紫红色砂岩为主夹紫红色泥岩、灰白色砂岩为主夹紫红色砂岩、灰白色砂岩、紫红色泥岩为主、灰白色砂岩夹灰绿色砂岩和粉红色砂岩。

It is because different types of soft rocks have different erosion and weathering levels that the categorization of soft rock samples becomes important in the study of the erosion resistance of soft rocks. The paper implements the algorithms of fuzzy cluster analysis via Matlab and applied to the classification of the soft rocks in Inner Mongolia. The results show that the soft rocks in the study area can be categorized into nine types, namely purple sandstone with celadon mudstone interbeds, purple sandstone,purple sandstone interbedded with offwhite sandstone, purple sandstone with purple mudstone interbeds,offwhite sandstone with purple sandstone, offwhite sandstone, purple mudstone, off white sandstone with celadon sandstone and pink sandstone interbeds.
