Abstract
The Blasting vibration can be reduced substantially by the employment of the controled blasting with continuous slot. Despite of this capability, the behavior concerning the dynamic fracture and vibration during the blasting process have not been clarified, and a numerical analysis method which can estimate these phenomena appropriately has not been developed. We propose a DEM-based analysis method which simulates the dynamic process consisting of both dynamic fracture and vibration. In this study a blasting experiment is also achieved for concrete blocks. The developed numerical method is then applied to its simulation. Through these analyses, the validity of the present method is discussed.
