Моделирование сейсмического поля в акустическом приближении двухфазных, иерархически неоднородных сред

Abstract

В работе рассмотрена задача моделирования сейсмического поля (случай распространения продольной волны с учетом только сжатия и растяжения среды) в слоистой среде с включениями иерархической структуры. Построены алгоритмы моделирования в сейсмическом случае для 2-D упругой и пористой иерархической неоднородности. Исследован вопрос отражения физических свойств однофазности и двухфазности в системе уравнений решения прямой динамической сейсмики в частотном варианте. In the paper is considered a problem for modeling seismic fields (case of longitudinal wave distribution with account of medium of compression and tension) in a layered medium with inclusions of hierarchic structure. It had been constructed an algorithms for 2D modeling of sound diffraction on porous fluid saturated intrusion of hierarchic elastic structure, located in the layer number J of N-layered elastic medium. It is analyzed the problem of reflection of physical features of one phase and two phase inclusions in the solution equations of the straight dynamical problem in a frequency variant.
