Abstract: This paper discusses the possible influence of grain shapes on the pore system of porous media and its seepage rules, as well as its research significance. By reviewing research results in related areas, discussions were made on the measurement method of grain shape, simulation method of grain shape and grain packing, visualization method of pore system, and experimental comparison method of seepage rules. The research result helps demonstrate the prospect of developing filter materials for water treatment and applying aggregate for dam construction.

Key words: grain shape ,  porous media ,  seepage ,  test  , simulation
