Abstract

Aiming at the existing problems in the field of coral sand, such as unclear micro-mechanism of the crushing process, inconsistent crushing quantification indicators, and disconnection between macro tests and micro mechanisms, laboratory tests including CT scanning, consolidation tests, triaxial compression tests, and repeated direct shear tests were carried out. The micro images of coral sand and macro properties such as density, permeability coefficient, compression modulus, rebound recompression modulus, cohesion, internal friction angle, residual cohesion, and residual internal friction angle were obtained. Through sieving tests before and after the tests, the relationship between pressure and coral sand particle breakage in different tests was obtained. The test results can provide technical support for the resource utilization of coral sand and the design and construction of coral sand foundations.
