Abstract:

This series of four HE tests at the Nevada Test Site was conducted to provide information for scaled predictions for the shallow underground and surface nuclear tests. The results of the HE tests were quite satisfactory, and predictions were made only if justified by the demonstrated adherence to scaling laws within the HE test series. In addition, correlation with results from 1951 Dugway tests in dry clay was obtained. In general, the air blast scaled as predicted in both duration and amplitude. Acceleration scaling was good for the amplitude of the first smoothed pulse, but the durations did not scale. The sharp and highly damped oscillation acceleration due to air blast scaled as did air-blast pressure, but its period, as expected, increased less rapidly than the scale factor. Air-coupled phenomena were prominent due to the relatively shallow scaled charge depths, and appeared to predominate in earth accelerations at large distances. Analytical work on this topic should aid in explaining many of the effects observed. A comparison with Dugway results for dry clay from similar tests indicates that the earth-acceleration amplitudes and durations were approximately inverse to each other for the two soils.
