effects of topography on blast vibration attenuation
Is there any research/publications that address ground borne vibration attenuation with changes in grade elevation? For example say there is construction blasting on a hill. The hole depth is < 10 ft. there is a ravine next to the hill that goes down 25 ft and then grade rises back up 15 ft...- sghvib
