In order to research the influences of different charge aspect ratio on damage effectives of concrete target on explosive effect Three-dimensional finite element dynamic code was adopted to analyze the processes of the explosion in concrete target, and gained the relationship between the radiuses of blasting Carter and different charge aspect ratio. The result shows that linear explosive charge with big charge aspect ratio is suitable for careen blasting, and linear explosive charge will help improve the cavity ratio and balance the detonation pressure, and aggregate charge is more useful in damaging the concrete target. The research results offer data reference for further theory studying and engineering designing
