Similitude requirements for predicting the response of dynamically loaded buried structures by means of scale models were developed by dimensional analysis and were checked experimentally. Hollow circular and square aluminum tubes were buried in dry compacted Ottawa sand and loaded dynamically by dropping a cylindrical weight on the soil surface. The strains induced on the inner surfaces of the tubes were measured using SR-4 strain gages. Complete strain-time curves and data indicating the variation of peak strain and rise time with depth of burial are presented. Reasonable correlation is obtained between both the peak strain data and the complete strain-time curves for the several structures tested. In general, the study demonstrates the feasibility and value of the use of scale models for the prediction of the dynamic response of underground structures.
