基于离散傅立叶变换的岩石节理形貌分析与随机重构
Fourier-based reconstruction of rock joint and the statistical analysis of its morphology
摘要
Abstract
In order to further study the numerical effect of the mesoscopic features on the macroscopic shear characteristics of the joint surface, this paper presents a Fourier-based morphology analysis method that can both quantitatively analyze the morphological characteristics of the joint samples and construct rock joint profile morphology in purpose. First, traditional roughness analysis and Fourier analysis were used to analyze 50224 measured joint profiles, and the empirical formula of Fourier parameters was obtained. Second, the range of Fourier parameters was determined for reverse reconstruction of different roughness joints. The research results provide an important basis for the rapid random reconstruction of joint profiles that conform to certain roughness characteristics and the establishment of a fully digital virtual test system.关键词
