摘要

The US Army Engineer Research and Development Center (ERDC) has designed and deployed an impulse measurement device (IMD) for a series of research experiments. The goal of the research was to quantify the influence of soil properties on the aboveground environment from the detonation of a bare explosive charge resting on the soil surface or from detonation of a shallow-buried explosive charge in the soil. Comparison of the experimental data with the results of the CTH calculations shows good agreement and indicate that the IMD performed as designed. The peak velocity and displacement data captured in the IMD were within 5 percent of the CTH calculated values. The displacement of the support structure recorded during the blast event was well below the design goals and proved to have little or no influence on the response of the IMD. The tests performed with the IMD are found to be successful in capturing critical information.
