Abstract For those rock-like brittle porous media，the water or salts crystallization states in pores are depend on factors as crystal type and pore shape，especially for the latter one，which control the whole crystal growth process and the magnitude and distribution of crystallization pressure between pore wall and crystal. Four kinds of ideal pore shapes were generalized from actual pores based on former researches as cylinder，sphere，elliptic cylider and ellipsoid. Cuvatures and key curvatures of these ideal shaps were calculated with the principles of differential geometry，and then formulas for the calculation of crystallization pressure magnitude and distribution within crystallization process were proposed. At last，took the crystallization of NaCl in elliptic cylindrical and ellipsoidal pores of different specifications for examples，calculated the distribution and variation of crystallization pressure within the growth of NaCl crystal，then compared and analysed the effects of specification on crystallization pressure.

Key words： rock mechanics porous medium ideal pore shapes crystallization crystallization pressure
