摘要
以往采用投影作图法确定岩石组构要素优选方位。本文依据模糊数学原理,提出解决该问题的一种新方法,它通过计算夹角余弦,建立组构要素模糊关系矩阵,做模糊聚类分析,直接确定优选方位。该方法也适用于节理统计与分组。
Preferred orientation of rock fabric elements is usually recognized by projecting and plotting contours. This paper presentrs a method with which the preferred orientation can be directly obtained by calculating the included angle cosine of fabric elements, forming fuzzy matrix of equivalence correlation and performing fuzzy cluster. The method is also suitable for joint statistics and classification.
