Аннотация:The utilization of seismic barriers for protection against the hazardous impact of natural ortechnogenic waves is an extremely promising emerging technology to secure buildings, structures andentire areas against earthquake-generated seismic waves, high-speed-transport-induced vibrations,etc. The current research is targeted at studying the effect of seismic-barrier shape on the reduction ofseismic-wave magnitudes within the protected region. The analytical solution of Lamb’s problemwas used to verify the adopted numerical approach. It was demonstrated that the addition ofcomplementary geometric features to a simple barrier shape provides the possibility of significantlyincreasing the resulting seismic protection. A simple genetic algorithm was employed to evaluatethe nontrivial but extremely effective geometry of the seismic barrier. The developed approach canbe used in various problems requiring optimization of non-parameterizable geometric shapes. Theapplicability of genetic algorithms and other generative algorithms to discover optimal (or closeto optimal) geometric configurations for the essentially multiscale problems of the interaction ofmechanical waves with inclusions is discussed.
