Abstract:

An analysis is presented of the scaling parameters which are important in scaling explosive-induced waves in earth materials and the effect of these waves on deep underground structures. Basically, two approaches to scaling are possible. Gravitational effects can be allowed for and material properties scaled, or gravitational effects can be ignored and material properties kept the same in the model as in the prototype. The study indicates that peak strain is dependent upon yield as well as other factors. The strain magnitude times the strain pulse period together with the energy level of the pulse appear to be reliable parameters for damage prediction. The analysis indicates that model scaling can be used to advantage to investigate a number of the factors which are important in the response of deep underground structures to explosive attack.
