Experimental investigation on contact explosion damage effect to fiber reinforced concrete slab with soil bedding

Experimental study of the response of the concrete, steel fiber reinforced concrete and polypropylene fiber reinfored concrete slab under blast loading was performed. The macroscopic damage is described, and the explosive compression coefficient values of three kind materials are obtained through apparent crater size fitting analysis. The ЛяхоB formula is used to fit the measured peak stress. The result shows that as the specimen thickness increases, the peak stress value will decrease, and the pressure value at same explosion distance will decrease as well. A formula that can be used to calculate the explosion perforation depth is obtained.
