Abstract: Crater formation, due to a low height-of-burst (HOB) explosive detonation, is caused by a combination of scouring, soil compression, and bulk soil displacement as the very high pressure detonation products interact with the underlying soil. Existing data for low HOB detonations over native soil indicate that the soil parameters clearly affect the size of the crater. In general, experience has shown that craters are largest for clayey soils and smallest for sandy soils. Mixed soils tend to result in craters of intermediate size. Likewise, wet soils tend to form larger craters than drier soils, although the direct relationship between water content percentage and crater size has not been quantified. Although the soil type and water content data are useful in determining the general size of an explosively-formed crater, it is desirable to develop methods of correlating crater size to specific, measurable soil properties. Such correlations would result in more accurate crater predictions and simplify the classification of a given soil material with respect to the expected crater size. This report details the planning, execution, and analysis of a series of experiments designed to quantify the variation in crater size from low HOB explosive detonations due to changes in soil parameters.
