P004 INVESTIGATIONS OF ELASTIC WAVES PROPAGATION IN MODELS OF SANDS SEDIMENTS E.B. SIBIRIAKOV and V.A. KULIKOV The Institute of Geophysics RAS (Sib. div.) Koptyg Avenue 3 6630090 Novosibirsk Russia Summary. We present a new approach to describe physical deforming processes in microinhomogeneous media in general in particularly sands sediments. Our approach is based on examination of individual interactions between particles. After it we used a new method of averaging of field forces for chaotic orientation of grains. The theoretical results are: velocity of P and S waves depends not only on average elastic modules of grains and porosity but also
