中文摘要	The effect of explosion spalling on anti-blast structures was investigated using limited thickness reinforced concrete slabs subjected to contact detonations. The damage patterns on the slabs in the tests were classified as explosive catering, spalling, perforation, and punch. The deformation and the dynamic damage processes of the slabs were simulated using LS-DYNA. Analysis of the parameters affecting the spalling led to a new spalling damage coefficient and damage classification method with a formula to calculate the spalling thickness. The results show that the numerical results agree well with the experimental data and that the spalling thickness is related to the amount of charge, the thickness, and the strength properties of the slab.
