摘要

用两相等效体的概念，根据Walsh公式和球形孔隙的弹性公式导出了多孔介质的孔隙率和体积模量之间的近似公式和精确公式，近似关系式不适用于较大的孔隙率。精确公式可以较好的适用于较大孔隙率。试验结果表明，精确公式能够很好地表达多孔介质孔隙率与体积模量之间的关系。

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.
