The basic principle of seismic design for underground structures is to increase the seismic capacity of the structure, reduce the impact of earthquake action on the structure, and ensure that the underground structure will not collapse or suffer serious damage during an earthquake. Generally, the sei...
Acoustic cavitation can be divided into inertial cavitation and non-inertial cavitation, which is mainly composed of three stages including nucleation, growth, and collapse of bubbles9,26. Inertial cavitation and non-inertial cavitation produce mechanical effects, while inertial cavitation leads to the ...
