Rock and Soil Mechanics
The pore is the place where the seepage occurs in the porous medium, which is inevitably related to the permeability of the medium. Due to the special material source and formation process, coral sand has completely different pore characteristics compared with terrestrial sand. Through a series of microscopic studies, the reason for the special pore properties of coral sand in essence was revealed. It is found that it is reasonable to describe the properties of pores from the aspect of pore shape, pore throat size and global connectivity. Among them, pore shape is measured by the shape factor. Pore throat …

Rock and Soil Mechanics
Coral sand is the only material for island land reclamation. Due to its special marine biogenesis and porosity structure, coral sand particles are easily crushed at normal level of engineering stress. In this study, drained triaxial shear tests were carried out on coral sand retrieved from a reclamation reef in the South China Sea to study the evolution law of the strength, deformation and particle breakage properties of coral sand with different levels of compaction and confining pressure. The comparative analysis of shear strength index is made between current study and previous investigations. The results show that strain softening and …
