Three-dimensional morphological characterization and quantitative roughness classification of loess joint surfaces

Key Points

• Distinct morphological characteristics of loess joint surfaces influence their structural stability, and roughness affects mechanical performance.
• Notable findings include a comprehensive classification of roughness types based on quantitative analysis, essential for practitioners in geology.
• Assessment using 3D morphology reveals how different joint surface profiles can impact erosion and geological formations over time.
• Implications suggest that classifications may enhance understanding of loess behavior, promoting systematic geological evaluations.
