Abstract: Based on Walsh equation and elastic equation of spherical holes, the approximate and accurate relationship between porosity and bulk modulus of porous medium are acquired. The approximate equation is not suit for big porosity very well. For big porosity the accurate equation should be used. Experiments show that the accurate equation can express the relationship of porosity and bulk modulus of porous medium well.

Key words: porous medium, bulk modulus, porosity, compression coefficient
