| Abstract: | Fine-grained coral soil, prevalent in tropical shallow marine environments, demonstrates significant potential as a natural engineering material. This study presents laboratory experiments employing digital image technology to investigate the effects of soil layer thickness and interface roughness on its cracking characteristics. By analyzing soil particle displacement during the cracking process, we examined the relationship between particle movement and the observed macroscopic crack patterns. The results indicate that both interface roughness and soil thickness substantially influence crack development and morphology. Increased interface roughness accelerates the cracking rate and transforms the pattern from overall contraction to multi-directional expansion, resulting in dense crack networks. Thinner soil layers facilitate more intricate crack formations, whereas thicker layers lead to more pronounced settling, longer and wider cracks, reduced horizontal cracking, and a simplified overall cracking pattern. This study elucidates the impact of interface roughness and soil layer thickness on the cracking behavior of fine-grained coral soil, providing valuable insights for its potential engineering applications.
