Through this scientific research work, we have studied the characteristics of explosives, shaped charges and their very history of use and application. We have also analyzed generally accepted methods of bridges demolition in accordance with NATO Allied doctrine and the doctrine of the Armed Forces of the Republic Croatia and have conducted a practical experiment of demolition of two reinforced concrete pillars with shaped charges that will have served as a scale model reinforced concrete load-bearing elements of a bridge. Explosive charges where the ratio between the longest and shortest sides is less than 3 : 1 are called concentrated explosive charges. If the ratio between the longest and the shortest sides is larger than 3 : 1, and the ratio between shorter sides less than 3 : 1, then the charges are called line or rail explosive charges. Shaped charges (in western literature) or cumulative charges (in Soviet/Russian literature) differ from other charges due to their capability of directing the energy released by the detonation. The detonation energy can be directed by making a cumulative space of regular dimentions and shaped in an explosive charge. If the cumulative space is coated with a thin layer of material, ussualy metal, this additionally amplifies the effect of the cumulative charge on the target object. Metal cladding is a source of heavy molecules and increases the kinetic energy of the jet that penetrates the target material. An additional increase in the action of cumulative charges is achieved by displacement cumulative charge at a certain distance from the target material. These characteristics of cumulative cutters can be used to demolish reinforced concrete elements with maximum efficiency as has been supported by the demolition experiment of reinforced concrete columns on vv „Cerovac“ and consequent measurements. The presented measurement results contribute to a better understanding of the cumulative process of line cumulative cutters and the mode of operation of line cumulative cutters.
