Аннотация
The paper is devoted to calculation of average elastic modules of microinhomogeneous medium. The new method, which is presented, is based on long-wave approximation, potential method of elasticity and averaging of medium parameters on orientation of structure. The using of fundamental solution of third kind (Weyl H.) as Green tensor gives a possibility to solve regular integral equations instead of singular ones. Velocities of P and S waves are increases with increasing of pore pressure, but increasing of S waves velocities is much more significant with respect to P ones, hence the ratio Vs/Vp is also increases.
