英文摘要	Abstract The permeability coefficient of calcareous sand is an important hydraulic parameter in reef engineering. The loading and permeation tests of calcareous sand and quartz sand under the same conditions were carried out by self-developed loadable sand permeability device, and the influencing factors were studied to obtain the calculation formula of the permeability coefficient of calcareous sand under load, containing void ratio e, particle gradation, permeability coefficient Ks and the relative crushing rate Br proposed by Hardin. The results show that under the same load, the permeability coefficient and compressive deformation of calcareous sand decrease more than that of quartz sand, and the relative breakage rate of calcareous sand increases with the increase of load, while there is exponential correlation between its Ks and Br. It can be concluded that the pores of calcareous sand are compacted under load, and the granule breakage leads to gradation change, which affects the permeability coefficient of calcareous sand.
