## Mathematical modelling of wave processes in a layed half-space with an additional tension

We consider the model of a vertically inhomogeneous medium, when one or more layers are under more stress. We suggested to use the matrix method of Thomson-Haskela for solving the problem to build field movements in order to use relevant analytical relations for solving the inverse problem in respect of stress tensor and / or parameters of the source. The results of mathematical modelling are simple in utilization and can be used for interpretation of seismic records.
