UNDERGROUND EXPLOSION EFFECTS

Abstract

Project 1.7 of Operation TEAPOT was concerned with the measurement of surface and subsurface effects of an underground explosion of a 1.2-kt nuclear burst (Shot 7). The measurements included free-field earth and airblast effects, as well as loading on underground structural devices. This report deals with the presentation and analysis of the free-field data only; the structural data have been transmitted to the appropriate agencies for their analysis. From the 76 channels installed on TEAPOT Shot 7, 75 usable records were obtained. The free-field quantities measured include air-blast pressure, earth acceleration, earth stress and strain, and permanent earth displacement. The results are discussed by phenomenon and, in each case, the TEAPOT data are compared with pretest predictions. Also, where data are available, comparisons are made with previous underground nuclear test results. Some aspects of seismology and soil mechanics as applied to underground explosion phenomena are presented and, finally, the most pertinent high explosives results from subsequent tests conducted at the TEAPOT location are summarized.
