Main Article Content
Abstract
The article describes the development of generalized seismogeological models for calculations based on the results of engineering-geological surveys, MASW method profiles from seismic surveys, and the HVSR method for determining the spectral ratio of microseismic vibrations from instrumental-seismometric surveys. Based on these data, seismogeological soil models were formed at different depths in the study area through a comprehensive assessment of the geological structure and the physical-mechanical and dynamic properties of soil layers. As a result, the seismic response of soil layers was modeled in accordance with international standards for the development of underground space, and seismic intensity maps (in scores) were developed for local specialists based on the maximum ground acceleration (PGA) values generated at different calculated depths of the underground environment, as well as seismic impact.
