Different backfill/backpack materials surrounding buried protective structures may have different effects regarding the interface forces between the soil and structure when exposed to explosive loading. The motivation of this work is to study these effects. The gauge concept consists of a grid of uncoupled plane areas using PVDF-film sensors between two mating surfaces to measure the pressure. The gauge is described in detail. This concept is attra
