摘要：
The new computational model for the seismic wave propagation in the initially prestressed media is proposed, the governing equations of which are written in terms of velocities, stress tensor and small rotations of element of the medium. The properties of wavefields in the prestressed medium are studied and some examples showing anisotropy of prestressed state are discussed. The staggered grid numerical method is developed for solving the governing equations of the model and numerical example is presented.
