Dynamic Rock Testing and Performance Study of Underground Structures Subjected to Blasting and Seismicity

The study of rock dynamics is important because many rock mechanics and rock engineering problems involve dynamic loading ranging from earthquakes to blast explosions. The subject deals with the distribution and propagation of loads, dynamic responses, and processes of rocks and rate-dependent properties, coupled with the physical environment. Rock dynamics has a wide range of applications in civil, mining, geological and environmental engineering. However, due to the additional "4th" dimension of time, rock dynamics remains, in the discipline of rock mechanics, a relatively more challenging topic to understand and to apply, where documented research and knowledge are limited. Much new researches are needed and are indeed on‐going. This paper covers the dynamic rock testing and study on the performance of underground structures subjected to blasting and earthquake vibrations
