Synergistic effect of fines content and void ratio on internal erosion: An intergranular state perspective

Key Points

• Internal erosion is significantly influenced by the synergistic effects of fines content and void ratio, causing potential soil instability.
• The analysis illustrates a notable increase in erosion rates with varying fines content and void ratios across multiple soil samples.
• Assessment of soil samples indicates that as fines content increases, void ratios contribute notably to erosion risk determination.
• These findings underscore the importance of considering both fines content and void ratio for better understanding soil erosion dynamics.
