Wave diagnostics of soil-building system and some patterns of seismic signal propagation in vertical planes of structures and continua
Under analysis are patterns of dynamic impulse propagation in buildings and structures when the impulse source is located atop or adown an objective. For the soil-building system diagnostics, it is suggested to use direct wave method based on recording of transit time and shape of seismic signal in assigned zones. This method allows detecting zones of underspeed seismic waves, which are, thus, the zones of lower strength and damage. The research findings reveal a factor appreciably influencing signal transit velocity bottom-up and top-down with the signal source situated atop or a down the vertical route. Evidently, this factor may be the field of gravity.
