Impact of elastic waves on bodies

Equally important is the study of effects when exposed to dynamic loads on underground structures. Therefore the creation of scientifically based methods for studying the stress - strain state of underground structures taking into account all these factors is an actual problem of great theoretical interest which has practical value for the construction of underground structures. This is evidenced by the increasing volumes of construction of underground pipelines tunnels underground stations mines for various purposes in seismic zones and the continuous development of methods for calculating and designing underground structures for dynamic effects.
