| 英文摘要 | Based on the interface shear tests, the macro- and meso-mechanical behaviors of interaction between coral sand and different structure surfaces are studied, in which CCD camera is used to capture digital images to analyze the evolution of the interaction band and a particle analysis apparatus is applied to studying the distribution characteristics of particle morphology. This study proposes four-stage evolution process based on the shear stress-strain curve. During the shear process, coral sand particles slide and rotate within the interaction band, causing the changes in shear stress and vertical displacement. In addition, the effects of structure surface roughness on shear strength, volume change and particle breakage are illustrated that the greater the roughness of slabs is, the larger the shear stress is, the more obvious the contraction effect is and the more the particles break. Furthermore, the change in particle's 3D morphology during the breakage will change not only their size but also other morphological characteristics with convergence and self-organization. |
