Abstract:

Stability the underground sensitive structures in order to reduce the damage of explosion on these structure including nuclear and military installations as well as energy site is an issue of great importance which cavers all the substructures and vital centers. The focus of this study is on the energy attenuation of onedimensional p-wave in rock mass. As a proposal to strengthen the structures applying virtual space in rock mass, analytical (based on wave reflection and transmission) and numerical study on P-wave attenuation are used. Analytical and numerical results have shown that any vacuum or cavity in rock mass greatly increases P-wave attenuation and that any rock material with strength mechanical properties in virtual space decreases attenuation and raises P-wave energy transmission. Moreover, these results can be a good source for intelligent designing of these structures.
