EXPERIMENTAL STUDY OF JOINT WORK GROUND CONSTRUCTION OF THIN-WALLED WITH UNDERGROUND SEISMIC EXPLOSION METHOD

This paper explores the behavior of underground structures and soil during seismic activity and underground explosions, emphasizing the energy dynamics and structural responses. The study conducted field experiments using underground explosions with charges ranging from 420 to 6540 kg. Observations focused on the stress-strain states of cylindrical thin-walled underground structures and their interaction with seismic waves. Key findings include wave propagation characteristics, energy distribution, and damping behaviors. The research also evaluates the kinetic energy transfer to structures and its correlation with soil energy. Experimental results provide insights into the stress distribution in soil and the deformation patterns of underground structures, enabling predictions of their behavior under seismic explosive conditions. These findings contribute to understanding and modeling the dynamic interactions in the "soil-structure" system during seismic events.
