A new computational method of effective elastic constants of the second and third order of multi-component geologic media is considered. Effects of the structure of crack-pore space on effective elastic Lame constants of the third order of model of quartz sandstone are investigated. With water saturation of micro-cracks of the format a =0,001, a =0,0001 non-linear effective elastic constants v1*, v2* change by several orders, non-linear effective elastic constant v3* changes considerably less.
