This paper presents the results of a combined experimental and numerical investigation into the blast loading generated by an explosive charge buried in an unsaturated soil. The dynamic response of the soil blast is quantified by its impulse imparted onto a high strength steel plate in a flying plate experiment. A 50 mm-thick plate of exposed area 500 mm by 500 mm is located at a constant stand-off distance of 400 mm above the surface of the soil. Upon detonation, the plate's heights are recorded and analysed using the initial velocity of the plate calculated from the flying time, while the rotation of the plates was shown to have negligible influence. Detailed unsaturated soil preparation, ..View full abstract
