英文摘要	Microscopic experiments were performed on the inner pores of calcareous sand particles to ascertain the special mechanical properties of calcareous sand. A femtosecond laser was used to cut the calcareous sand particles to obtain cross-sections of particle. The micrographs of the inner pores of the sand particles were taken with a three-dimensional video microscopic visualiser. The parameters of the pores were analysed through the micrograph processing with MATLAB. The results show that calcareous sand has relatively low surface porosity. The surface porosities of particles with pore diameter >2 mm and those in the range of 1-2 mm are 0.66 and 1.07% respectively. Based upon the number of pores, the distribution characteristics of the pores show that there are fewer macropores but more micropores in the sand. In terms of the area of pores, micropores occupy a smaller proportion than macropores. It was found that 65% of the pores have area < 1 mu m(2), and 55% or more of them are equiaxed pores.
